Mechanisms for proper alignment of different components are provided internally. This way the user does not have to care for proper orientation of the elements. Macros for convenient definition of new user-defined components are also provided. \section{Concept and General Behavior}\label{sec:general} This section introduces into the basic concepts of the package design and explains the parameters and commands which are supported by most optical objects. \subsection{Concept} The objects provided by \nxLPack{pst-optexp} can be differentiated into two different categories: free-ray and fiber-optical objects. The free-ray units are subdivided in two different kinds: dipoles which require two reference points for alignment and do not alter the direction of passing light beams (e.g. lenses and retardation plates) and tripoles which work in reflection and require three reference points (mirrors, gratings, beamsplitters etc.). For free-ray setups one usually has a few straight light paths in which several different objects are to be arranged. In this case it is very convenient to define only two nodes for each light path. The objects are placed on this light path using the different positioning parameters (see Sec.~\ref{sec:positioning}) of the package. After having arranged everything, the beams themselves are drawn. If objects with multiple internal reflections (e.g. prisms, see Sections \ref{sec:doveprism}, \ref{sec:prism} -- \ref{sec:ppprism}) or objects without internal beams (e.g. optical diodes, see Sec.~\ref{sec:optdiode}) are involved. The different possibilities are explained in Sec.~\ref{sec:connecting}. The fiber-optical objects can be classified as dipoles, tripoles and quadrupoles which have a corresponding number of fiber connections. Their handling differs in some aspects from the free-ray objects. The fiber optics are directly connected to the reference nodes. Every input and output fiber can be flexibly customized for each object (see Sec.~\ref{sec:styles}). Positioning of the fiber dipoles is handled equivalently to the free-ray dipoles. Tripoles and quadrupoles can be found only as different coupler types. Their positioning mechanisms are a bit more involved and explained in Sec.~\ref{sec:coupler}. Some hybrid dipoles (optbox, detector etc.) can be used both as fiber-optical or free-ray elements. The way they are treated regarding the connections to the reference points can be controlled by the parameters explained in Sec.~\ref{sec:connecting}. \subsection{General Settings} \begin{description} \paramitem{angle}{}{0} \paramitem{compshift}{}{0} \paramitem{optional}{}{false} \paramitem{showoptdots}{}{false} \end{description} \parameter{optional} can be used with every object and marks it as optional. The style of an optional element can be configured by changing the psstyle \styleshape{OptionalStyle}. \parameter{showoptdots} draws some internal nodes which are used to place the object and the label. The black points are used for positioning, the red points mark the label references. \medskip \begin{LTXexample}[pos=t, vsep=0.8cm] \begin{pspicture}[showgrid=true](8,2) \psset{beam} \lens[optional](0,1)(3,1){L} \mirror[showoptdots](4,1)(7,1)(7,0){mirror} \end{pspicture} \end{LTXexample} \medskip \subsection{Using PSStyles}\label{sec:styles} \begin{description} \styleitem{OptionalStyle}{} \paramitem{addtoOptComp}{}{} \paramitem{newOptComp}{}{} \styleitem{OptComp}{} \end{description} \styleshape{OptComp} affects only the appearence of the optical components. This was introduced, because using only the standard graphics parameters changes also the connections that are drawn within the component. \medskip \begin{LTXexample}[pos=t, vsep=0.8cm] \begin{pspicture}[showgrid=true](8,2) \psset{beam} \addtopsstyle{OptComp}{linestyle=dashed, dash=2pt 2pt} % wrong, also beam width is changed \mirror[linewidth=3\pslinewidth](0,1)(3,1)(3,0){mirror} % correct result \mirror[addtoOptComp={linewidth=3\pslinewidth}](5,1)(7,1)(7,0){mirror} \end{pspicture} \end{LTXexample} \medskip \subsection{Positioning}\label{sec:positioning} \begin{description} \paramitem{position}{}{\{\}} \paramitem{abspos}{}{\{\}} \end{description} \noindent\parameter{position} is equivalent to the \parameter{npos} parameter of \cs{ncput} (can be any number from 0 to 1) and controls the relative position of object between the two reference points. It is only not available for the free-ray tripoles. The parameter \parameter{abspos} allows absolute positioning between the two reference nodes. Its value is given in psunits. \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \lens[beam, position=0.8](0,1.2)(3,1.2){L} \end{pspicture} \end{LTXexample} \bigskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \lens[beam, abspos=1](0,1.2)(3,1.2){L} \end{pspicture} \end{LTXexample} \medskip \subsection{Labels}\label{sec:labels} \begin{description} \paramitem{labeloffset}{}{0.8} \paramitem{labelangle}{}{0} \paramitem{labelstyle}{}{\cs{small}} \paramitem{labelalign}{\footnote{\refstringexplanation}}{c} \paramitem{labelref}{relative|relgrav|global}{relgrav} \paramitem{label}{ }{} \end{description} \noindent\parameter{labeloffset} specifies the offset from the label reference node of the object which is mostly the center. \parameter{labelstyle} defines the textstyle that is used to typeset the label and \parameter{labelalign} corresponds to the refpoint of \cs{rput}. The parameter \parameter{labelref} sets the reference coordinate system for the \parameter{labelangle} and the orientation of the label text. The detailed behaviour is best illustrated looking at the following three examples. \medskip \begin{LTXexample}[width=5cm] \begin{pspicture}(-2,-2)(2.5,2) \multido{\i=0+45}{8}{% \optbox[endbox, labelref=relative, labeloffset=0, optboxwidth=1, optboxheight=0.6](0,0)(1;\i){\i} } \end{pspicture} \end{LTXexample} \bigskip \begin{LTXexample}[width=5cm] \begin{pspicture}(-2,-2)(2.5,2) \multido{\i=0+72}{5}{% \optbox[endbox, labelref=relgrav, optboxwidth=1, optboxheight=0.6](0,0)(1;\i){\i} } \end{pspicture} \end{LTXexample} \bigskip \begin{LTXexample}[width=5cm] \begin{pspicture}(-2,-2)(2.5,2) \multido{\i=0+72}{5}{% \optbox[endbox, labelref=global, optboxwidth=1, optboxheight=0.6](0,0)(1;\i){\i} } \end{pspicture} \end{LTXexample} \medskip \parameter{label} simplifies the simultaneous change of more than one label-related parameter. It takes up to four space-separated arguments. Unchanged arguments may be specified with a dot. \medskip \begin{LTXexample}[width=5cm] \begin{pspicture}[showgrid=true](0,0)(3,3) \psset{endbox, beam} \optbox[label=1 -45](1,0)(2,1){label} \optbox[label=0 . . relative](0.6,0.6)(0.6,1.6){label} \end{pspicture} \end{LTXexample} \medskip \subsection{Named Objects}\label{sec:namedobj} \begin{description} \paramitem{compname}{}{\{\}} \end{description} \noindent Every \nxLPack{pst-optexp} object of an experimental setup can be assigned a name that is unique within one pspicture environment. The name is defined with the parameter \parameter{compname} which is defineable only directly within a \nxLPack{pst-optexp} object: \medskip \begin{lstlisting} \optbox[compname=MyBox](A)(B){Box} % valid use of 'compname' \psset{compname=MyName} % not valid, gives an error \end{lstlisting} \medskip \noindent With this naming mechanisms one can access some special nodes of the component at any time after its definition: \begin{table}[H] \centering \addtolength{\extrarowheight}{1.5mm} \begin{tabularx}{.8\linewidth}{TX} \toprule \multicolumn{1}{l}{node name} & description\\ \midrule ExtNode & Node for external connections (\emph{external node})\\ Intern1 & Node which should be connected to the first reference node. In the text we refer to this node as \emph{left outer node} \\ Intern2 & First internal node. As the nodes with higher numbers it is only available for objects with multiple internal beams (e.g. dove prism, see Sec.~\ref{sec:doveprism}). They are called \emph{internal nodes}.\\ \multicolumn{1}{c}{\vdots} & \\ InternN & Node which should be connected to the second reference node. In the text this node is referred to as \emph{right outer node}\\ \bottomrule \end{tabularx} \caption{Naming conventions for special nodes which are created by named objects and can be accessed by the user after definition of the object.} \end{table} If \parameter{compname} is empty, the external node has the name \nodename{ExtNode} and will be overwritten by any following object. The outer nodes are not accessible to the user and will also be overwritten by following object. The internal nodes are deleted after the object's definition. These named objects are used to create permanent external nodes (see Sec.~\ref{sec:extnode}) and to connect objects after their definition (see Sec.~\ref{sec:connecting}). \subsection{Nodes For External Usage}\label{sec:extnode} \begin{description} \paramitem{extnode}{\footnote{\refstringexplanation}}{\{\}} \end{description} \noindent Some of the objects can provide a supplementary node for additional connections. A laser diode may be connected for example to a frequency synthesizer (use package \nxLPack{pst-circ}) or a detector to a computer. \parameter{extnode} controls the position of the additional node and takes a \paramvalue{} as its argument. By default this parameter is empty (\paramvalue{\{\}}) and no node is created. The name of the new node depends on the \parameter{compname} parameter (see Sec.~\ref{sec:namedobj} for naming conventions). If \parameter{compname} is empty the new node is named \nodename{ExtNode} by default and overwritten by following objects. Table.~\ref{tab:nodes} shows all objects which provide an external node. Some allow any possible \paramvalue{} for \parameter{extnode}, others have only one reasonable possibility (e.g. piezo mirror, see Sec.~\ref{sec:mirror}) which does not depend on the actual value of \parameter{extnode}. \bigskip \begin{LTXexample}[pos=t, vsep=8mm] \begin{pspicture}[showgrid=true](11,3) \psset{conn=o-o, labelangle=-90, labeloffset=0.3} \optbox[extnode=tl](0,2.5)(3,2.5){\texttt{tl}}\psdot(ExtNode) \optbox[extnode=l](0,1.5)(3,1.5){\texttt{l}}\psdot(ExtNode) \optbox[extnode=bl](0,0.5)(3,0.5){\texttt{bl}}\psdot(ExtNode) \optbox[extnode=t](4,2.5)(7,2.5){\texttt{t}}\psdot(ExtNode) \optbox[extnode=c](4,1.5)(7,1.5){\texttt{c}}\psdot(ExtNode) \optbox[extnode=b](4,0.5)(7,0.5){\texttt{b}}\psdot(ExtNode) \optbox[extnode=tr](8,2.5)(11,2.5){\texttt{tr}}\psdot(ExtNode) \optbox[extnode=r](8,1.5)(11,1.5){\texttt{r}}\psdot(ExtNode) \optbox[extnode=br](8,0.5)(11,0.5){\texttt{br}}\psdot(ExtNode) \end{pspicture} \end{LTXexample} \begin{table}[H] \centering \begin{tabular}{llc} \toprule Object & possible extnode positions &\\ \midrule % \cs{optbox} & all (any combination of \paramvalue{t}, \paramvalue{r}, \paramvalue{l} and \paramvalue{b}) & \begin{pspicture}[shift=-0.3](0,-0.4)(1,0.4) \psframe(0,-0.25)(1,0.25) \psdot(0,-0.25)\psdot(0.5,-0.25)\psdot(1,-0.25) \psdot(0,0)\psdot(0.5,0)\psdot(1,0) \psdot(0,0.25)\psdot(0.5,0.25)\psdot(1,0.25) \end{pspicture}\\ % \cs{mirror} & one fixed position (only for \parameter{mirrortype=piezo}) & \begin{pspicture}[shift=-0.3](1,0.8) \mirror[mirrortype=piezo,extnode=t](0,0.4)(0.5,0.4)(0.5,0){}\psdot(ExtNode) \end{pspicture}\\ % \cs{optdetector} & one (for \parameter{dettype=round}) & \begin{pspicture}[shift=-0.3](1,0.8) \optdetector[detsize=0.6, extnode=r](0,0.4)(0.5,0.4){} \psdot(ExtNode) \end{pspicture}\\ % & all (for \parameter{dettype=diode})& see \cs{optbox}\\ \cs{optmzm} & all& see \cs{optbox}\\ \cs{optfilter} & all & see \cs{optbox}\\ \cs{optswitch} & all & see \cs{optbox}\\ \cs{fiberdelayline} & all & see \cs{optbox}\\ \bottomrule \end{tabular} \caption{The objects which may provide an external node when parameter \parameter{extnode} is not empty. Some allow different positions of the node and for some only a fixed node makes sense.}\label{tab:nodes} \end{table} \subsection{Connecting Objects}\label{sec:connecting} \begin{description} \paramitem{conn}{}{-} \item[\param{fiber}:] alias for \parameter{conn=f-f} \item[\param{beam}:] alias for \parameter{conn=o-i} \paramitem{connjoin}{}{1} \end{description} \noindent Simple experimental setups with a few objects can usually be realized by defining some nodes, arranging the object in between and drawing the beams at the end. If, however, objects with changed internal optical path (all the prisms) or without visible internal beam (optical diode) are involved, this simple method is not applicable anymore. For this case several different possibilities of connecting objects are available: \parameter{conn} specifies the kind of connections in front of and behind the object. Its syntax is analogous to the PSTricks \parameter{arrows} parameter. By default it is set to \paramvalue{-} and no connections are drawn. Tab.~\ref{tab:conn} lists all possible values and their scope for the \paramvalue{}. \begin{table}\centering \addtolength{\extrarowheight}{1.5mm} \begin{tabularx}{0.9\textwidth}{TXl} \toprule \multicolumn{1}{l}{conn style} & description & scope\\ \midrule i & Draw beam from the first reference node to its assigned outer node and then through all internal nodes and end at the other outer node. & \multirow{3}{*}{optexp objects}\\ o & Draw beam from the first reference node to its assigned outer node. & \\ f & Draw fiber from the first reference node to its assigned outer node. & \\ \midrule a & Left outer node & \multirow{4}{*}{\cs{drawbeam} macro}\\ A & Connect left outer node to all internal nodes and then to the right outer node & \\ b & Right outer node & \\ B & Connect right outer node to all internal nodes and then to the left outer node & \\ \bottomrule \end{tabularx} \caption{All possible values for the \paramvalue{}, their detailed description and scope.}\label{tab:conn} \end{table} The first letter (before the dash) in the \paramvalue{} refers to which object node the first reference node should be connected to, the second letter (after the dash) affects the connection from the object to the second reference node. Tab.~\ref{tab:conn} lists all possibilities for \parameter{conn} within an object: \paramvalue{f} draws a fiber connection and \paramvalue{o} a beam connection to the appropriate outer node. \paramvalue{i} draws a beam connection to the appropriate outer node and then through all internal nodes and end at the other outer node. The boolean parameter \parameter{beam} is an alias for \parameter{conn=o-i}. The beam style is controlled by the psstyle \styleshape{Beam} which can be changed using \cs{newpsstyle} and \cs{addtopsstyle}. All fiber-optical units define \parameter{conn=f-f} which means that input and output connections are \paramvalue{f}ibers. The boolean parameter \parameter{fiber} is an alias for \parameter{conn=f-f}. The fiber connection style can be changed by adapting the \styleshape{Fiber*} styles (see Sec.~\ref{sec:fiberstyles}). The way how to really use this kind of connections should become more clear after looking at the following examples in this section. \medskip \begin{LTXexample}[width=4.5cm] \begin{pspicture}[showgrid=true](4,5) \addtopsstyle{Beam}{arrows=->, arrowscale=1.5} \psset{labeloffset=0} \doveprism[conn=o-](0,4.5)(4,4.5){\texttt{o-}} \doveprism[conn=i-](0,3.5)(4,3.5){\texttt{i-}} \doveprism[conn=-o](0,2.5)(4,2.5){\texttt{-o}} \doveprism[conn=-i](0,1.5)(4,1.5){\texttt{-i}} \optbox[conn=-f](0,0.5)(4,0.5){\texttt{-f}} \end{pspicture} \end{LTXexample} \medskip The following example shows how this \parameter{conn} parameter can be used in some kinds of experimental setups using objects with changed internal optical path (here a penta prism). Instead of drawing the beam at the end with a \cs{psline}, the beams are created at definition time of the respective object. \begin{LTXexampleFloat} \begin{LTXexample}[width=4.5cm] \begin{pspicture}[showgrid=true](4,5) \pnode(1,1){A}\pnode(1,4){G}\pnode(3,4){B} \optbox[endbox, labelref=relative, labeloffset=0, optboxwidth=1](G)(A){Laser} \lens[lens=0.5 0.5 0.5, abspos=0.3](A)(G){} \pinhole[abspos=0.5](A)(G){} \lens[lens=2, abspos=0.8](A)(G){} \lens[abspos=2, labelangle=180](A)(G){L} \optplate[abspos=1.5, labeloffset=1](A)(G){SLM} \lens[abspos=1](G)(B){L} \optbox[endbox, labeloffset=0, optboxwidth=1](G)(B){CCD} \pentaprism[beam, labeloffset=1](A)(G)(B){PP} \end{pspicture} \end{LTXexample} \caption{Code example on how to use the \parameter{conn} parameter in experimental setups.}\label{lst:conn} \end{LTXexampleFloat} This method works unless objects without internal beams (e.g. an optical diode, Sec.~\ref{sec:optdiode}) or with internal reflections (e.g. a Dove prism, Sec.~\ref{sec:doveprism}) are used in the straight light paths of the setup. One possibility would be to create additional nodes, but this may be not very comfortable. Therefore, \nxLPack{pst-optexp} provides a macro \cs{drawbeam} which connects a named object (Sec.~\ref{sec:namedobj}) to another named object or a node. \medskip \begin{lstlisting} \drawbeam[conn=...]{}{} \end{lstlisting} \medskip \noindent If \paramvalue{} or \paramvalue{} is a node, it must be written including the round braces. The call \medskip \begin{lstlisting} \drawbeam{Obj}{(1;45)} \end{lstlisting} \medskip\noindent connects the named object \nodename{Obj} to the node. The type of beam connection which \cs{drawbeam} draws is again controlled by the parameter \parameter{conn}. Almost every optical object does not have distinguished inputs and outputs and can be used in either directions. Therefore, it does not make sense to speak about `input` and `output` when referring to the object nodes, but rather about node A (\nodename{left outer node}) and node B (\nodename{right outer node}). Consequently, the two letters of parameter \parameter{conn} can take the values \paramvalue{a}, \paramvalue{A}, \paramvalue{b} or \paramvalue{B} when used together with \cs{drawbeam}. The detailed descriptions of the individual possibilities are listed in Tab.~\ref{tab:conn}. The letter before the dash in \parameter{conn} refers to the \paramvalue{} object, the other one to the \paramvalue{} object. Again, the next examples should clearify how to apply the \cs{drawbeam} macro together with the different \parameter{conn} settings. \begin{LTXexampleFloat} \begin{LTXexample}[width=4.5cm] \begin{pspicture}[showgrid=true](4,6) \psset{labeloffset=0.6} \addtopsstyle{Beam}{arrows=->, arrowscale=1.5} \doveprism[compname=Dove1](0,0.8)(3,0.8){Dove1} \drawbeam[conn=b-]{Dove1}{(3,0.8)} \doveprism[compname=Dove2](0,2.3)(3,2.3){Dove2} \drawbeam[conn=B-]{Dove2}{(3,2.3)} \doveprism[compname=Dove3](0,3.8)(3,3.8){Dove3} \drawbeam[conn=-a]{(0,3.8)}{Dove3} \doveprism[compname=Dove4](0,5.3)(3,5.3){Dove4} \drawbeam[conn=-A]{(0,5.3)}{Dove4} \end{pspicture} \end{LTXexample} \end{LTXexampleFloat} With the help of the \cs{drawbeam} macro we can adapt Listing~\ref{lst:conn} to use an optical diode before the beam clearing and connect it to the other components. In order to illustrate the beams that are drawn by the different mechanisms, they are colorcoded in the resulting Listing~\ref{lst:conn2}: \emph{green} is the direct connecting of the optical diode, \emph{red} is the \cs{drawbeam} connection and \emph{blue} the direct connecting of the penta prism. \begin{LTXexampleFloat} \begin{LTXexample}[width=4.5cm] \begin{pspicture}[showgrid=true](4,6) \pnode(1,1){A}\pnode(1,5){G}\pnode(3,5){B} \optbox[endbox, labelref=relative, labeloffset=0, optboxwidth=1](G)(A){Laser} \lens[lens=0.5 0.5 0.5, abspos=1.5](A)(G){} \pinhole[abspos=1.7](A)(G){} \lens[lens=2, abspos=2](A)(G){} \lens[abspos=3, labelangle=180](A)(G){L} \optplate[abspos=2.5, labeloffset=1](A)(G){SLM} \lens[abspos=1](G)(B){L} \optbox[endbox, labeloffset=0, optboxwidth=1](G)(B){CCD} \optdiode[abspos=0.8, conn=o-, compname=OD](A)(G){OD} \addtopsstyle{Beam}{linecolor=blue} \pentaprism[conn=-i, labeloffset=1, compname=PP](A)(G)(B){PP} \addtopsstyle{Beam}{linecolor=red} \drawbeam[conn=b-a]{OD}{PP} \end{pspicture} \end{LTXexample} \caption{More soffisticated code example which employs both connecting methods. The beam connections are colorcoded: \emph{green} is the direct connecting of the optical diode, \emph{red} is the \cs{drawbeam} connection and \emph{blue} the direct connecting of the penta prism.}\label{lst:conn2} \end{LTXexampleFloat} \newpage \section{Free-Ray Objects} The general appearance of all objects can be customized using the standard PSTricks parameter like \parameter{linewidth} or \parameter{fillstyle}. Some components allow changing a special part (e.g. for a piezo mirror) for which they use certain psstyles. For the automatic beam connections the \styleshape{Beam} style is used. \subsection{Lens}\label{sec:lens} \begin{description} \paramitem{lensheight}{}{1} \paramitem{lenswidth}{}{0.2} \paramitem{lensradius}{ []}{\{\}} \paramitem{lensradiusleft}{}{1} \paramitem{lensradiusright}{}{1} \paramitem{lens}{ [ [ []]]}{\{\}} \paramitem{thicklens}{}{false} \end{description} \medskip \begin{LTXexample}[width=5.5cm] \begin{pspicture}[showgrid=true](5,6) % concave lenses \pnode(0,5){A}\pnode(5,5){B} \psline[style=Beam](A)(B) \lens[position=0.2](A)(B){L} \lens[lensradius=-1,position=0.5](A)(B){L} \lens[lens=-1.5 1,position=0.7](A)(B){L} % convex lenses \pnode(0,3){A}\pnode(5,3){B} \psline[style=Beam](A)(B) \lens[position=0.2,lens=1 -1](A)(B){L} \lens[lens=0 -1](A)(B){L} \lens[lens=1 0,position=0.7](A)(B){L} % thick lenses \pnode(0,1){A}\pnode(5,1){B} \psline[style=Beam](A)(B) \lens[position=0.3, lens=-1.5 1 1 0.5, thicklens](A)(B){thicklens} \lens[lens=0 -1, position=0.7, fillstyle=solid, fillcolor=blue!30!white](A)(B){lens} \end{pspicture} \end{LTXexample} \medskip The shape of a lens is defined by its two surface radii. A negative radius gives a concave, a positive radius a convex and a radius of \texttt{0} a plain surface. The parameters \parameter{lensradiusleft} and \parameter{lensradiusright} allow to define independent values for both surfaces. \parameter{lensradius} sets both curvatures to the same value. Usually only \parameter{lensheight} and the two radii are used to construct the lens. The thickness (or width) is determined automatically. Manually controlling the thickness of the lens can be achived by setting \parameter{thicklens} to \paramvalue{true}. Then \parameter{lenswidth} is used as width of the lens at its waist. Finally, the parameter \parameter{lens} allows the definition of all relevant lens parameters at once. It consists of one up to four space-separated numbers. The first one gives the left radius. If no further value is set, the right radius will be set to the same value and all other parameters are left unchanged. Using two numbers defines two different radii. The third optional value defines the \parameter{lensheight} and the fourth one the \parameter{lenswidth} which is use only if \parameter{thicklens} is set to \parameter{true}. \textbf{Compatibility:} The whole implementation of the lens was changed in version 1.2. It allows a much more flexible definition of different lens types. However, I could not get full compatibility with the older way to define lens using only \parameter{lensheight} and \parameter{lenswidth}. To use this old behaviour, you have to set the \parameter{lenstype} explicitly, but then you have no access to the new features! All users are encouraged to adapt their code to use the new parameters, as the old code will be removed in future versions. \medskip \subsection{Optical Plate} \begin{description} \paramitem{plateheight}{}{1} \paramitem{platelinewidth}{}{2\cs{pslinewidth}} \paramitem{angle}{}{0} \end{description} \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \optplate[beam](0,1.2)(3,1.2){filter} \end{pspicture} \end{LTXexample} \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \optplate[angle=10, beam](0,1.2)(3,1.2){glass plate} \end{pspicture} \end{LTXexample} \medskip \subsection{Retardation Plate} \begin{description} \paramitem{plateheight}{}{1} \paramitem{platewidth}{}{0.1} \end{description} \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \pnode(0,1.2){A} \pnode(3,1.2){B} \optretplate[beam](A)(B){$\nicefrac{\lambda}{2}$} \end{pspicture} \end{LTXexample} \medskip \subsection{Pinhole} \begin{description} \paramitem{outerheight}{}{1} \paramitem{innerheight}{}{0.1} \paramitem{phlinewidth}{}{2\cs{pslinewidth}} \end{description} \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \pnode(0,1.2){A} \pnode(3,1.2){B} \pinhole[beam](A)(B){PH} \end{pspicture} \end{LTXexample} \medskip \subsection{Crystal}\label{sec:crystal} \begin{description} \paramitem{crystalwidth}{}{1.4} \paramitem{crystalheight}{}{0.6} \paramitem{caxislength}{}{0.6} \paramitem{caxisinv}{}{false} \paramitem{voltage}{}{false} \paramitem{lamp}{}{false} \paramitem{lampscale}{}{0.3} \paramitem{angle}{}{0} \paramitem{rotateref}{}{c} \end{description} \noindent For a discussion of the \parameter{angle} and \parameter{rotateref} parameters see Sec.~\ref{sec:box} about boxes. \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \pnode(0,1.2){A} \pnode(3,1.2){B} \crystal[fillstyle=solid, fillcolor=yellow!90!black, labelangle=-45, labeloffset=1.2, voltage, lamp, beam](A)(B){SBN:Ce} \end{pspicture} \end{LTXexample} \medskip \subsection{Box}\label{sec:box} \begin{description} \paramitem{optboxheight}{}{0.8} \paramitem{optboxwidth}{}{1.4} \paramitem{endbox}{}{false} \paramitem{angle}{}{0} \paramitem{rotateref}{\footnote{\refstringexplanation}}{c} \paramitem{refractiveindex}{}{\{\}} \end{description} \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \optbox[beam](0,0)(3,2){box} \end{pspicture} \end{LTXexample} \bigskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \optbox[beam, endbox](0,0)(1.7,1){box} \end{pspicture} \end{LTXexample} \bigskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \pnode(0,0){A} \pnode(1.7,1){B} \optbox[beam, endbox, labelref=relative, labeloffset=0](A)(B){box} \end{pspicture} \end{LTXexample} \medskip \noindent The parameter \parameter{angle} describes the tilt of the box relative to the reference line defined by the two reference nodes.

The styles can be redefined with \cs{newpsstyle} or changed with \cs{addtopsstyle}. For optical systems it is not possible to define a unique input and a unique output as most components can be used bidirectionally. Therefore, I refer to the input as the connections on the left of the object and to the output the ones on the right side. The basic style is \styleshape{Fiber} which is the parent of all other styles. \styleshape{FiberIn} inherits from \styleshape{Fiber} and defines the style of the input fiber. Analogously \styleshape{FiberOut} controls the style of the output fiber. If you want to change the input and output fiber styles you should use \cs{addtopsstyle} as then the inheritance from the parent style \styleshape{Fiber} remains. The other psstyles are used only by the various fiber couplers (\cs{optcoupler}, \cs{wdmcoupler} and \cs{wdmsplitter}). \styleshape{FiberIn1} affects the upper input fiber, \styleshape{FiberIn2} the lower input fiber, \styleshape{FiberOut1} the upper output fiber and \styleshape{FiberOut2} the lower output fiber. If the object has only one input (e.g. \cs{wdmsplitter}), \styleshape{FiberIn} is used. All fiber connections are drawn as \cs{pccurve} which means that also the curvature and the input and output angles of each connection can be changed as you will see in a following code example. \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,3) \addtopsstyle{FiberIn}{ArrowInside=->, arrowscale=1.2} \addtopsstyle{FiberOut2}{linecolor=blue} \optcoupler(0,2.5)(0,0.5)(3,2.5)(3,0.5){50~\%} \end{pspicture} \end{LTXexample} \medskip In addition to the psstyles there exist corresponding \parameter{newFiber\ldots} and \parameter{addtoFiber\ldots} parameter keys for each of them. \medskip \begin{lstlisting} \psset{addtoFiberIn={arrows=->, arrowscale=1.3}} \end{lstlisting} \medskip \noindent is equivalent to \medskip \begin{lstlisting} \addtopsstyle{FiberIn}{arrows=->, arrowscale=1.3} \end{lstlisting} \medskip \noindent Accordingly \parameter{newFiberIn} corresponds to \cs{newpsstyle\{FiberIn\}\{\ldots\}}. At first glance these keys make no sense. The reason why I introduced them was to be able to define special couplers with \cs{newpsobject}. This is only possible if all modifications can be expressed as parameter keys. Consider for example a WDM splitter which only couples out a certain spectral range of the input and you want to mark the output with an arrow: \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \newpsobject{mywdmsplitter}{wdmsplitter}{addtoFiberOut1={arrows=->, arrowscale=1.3, linecolor=blue}, labelangle=180, align=bottom} \mywdmsplitter(0,0.5)(3,1.5)(3,0.5){blue band} \end{pspicture} \end{LTXexample} \medskip Or if you need a coupler with a particular input angle you can do it be extending the appropriate fiber style: \medskip \begin{LTXexample}[width=3.5cm] \begin{pspicture}[showgrid=true](3,2) \newpsobject{mycoupler}{optcoupler}{addtoFiberIn2={angleA=90}, align=top} \mycoupler(0.5,1.5)(0.5,0.5)(2.5,1.5)(2.5,0.5){} \end{pspicture} \end{LTXexample} \medskip \section{Defining New Objects} \subsection{Customized Versions of Existing Macros} The easiest way to define your own components is to use the \cs{newpsobject} macro. With this you can define a new component using predefined objects with a set of options. These options serve only as default values and can be overridden when calling the macro. The following examples defines a new object \cs{sbn} for the special crystal used in Sec.~\ref{sec:crystal}. \medskip \begin{LTXexample}[width=3.5cm] \newpsobject{sbn}{crystal}{voltage, lamp, labelangle=45, labeloffset=1.2, fillstyle=solid, fillcolor=yellow!90!black} \begin{pspicture}[showgrid=true](3,2) \sbn(0,1)(3,1){SBN:Ce} \psline[style=Beam](0,1)(3,1) \end{pspicture} \end{LTXexample} \medskip \begin{LTXexample}[width=3.5cm] \newpsobject{pumpcoupler}{wdmcoupler}{align=top, labelangle=180, labeloffset=0.5,addtoFiberIn2={ArrowInside=->, arrowscale=2}} \begin{pspicture}[showgrid=true](3,2) \pumpcoupler(0,1)(0,0)(3,1){Pumpcoupler} \end{pspicture} \end{LTXexample} \medskip Or if you need more than one type of lenses several times in your setup it is very cumbersome to specify all parameters every time. \medskip \begin{LTXexample}[width=5.5cm] \newpsobject{MOLensIn}{lens}{lens=0.5 0.5 0.5} \newpsobject{MOLensOut}{lens}{lens=1.5 1.5 1.5} \begin{pspicture}[showgrid=true](5,2) \pnode(0,1){A}\pnode(5,1){B} \MOLensIn[abspos=0.5](A)(B){} \MOLensOut[abspos=1](A)(B){} \MOLensOut[abspos=4](A)(B){} \MOLensIn[abspos=4.5](A)(B){} \psline[style=Beam](A)(B) \end{pspicture} \end{LTXexample} \medskip \subsection{Defining New Objects}\label{sec:newobj} Since version 1.2 \nxLPack{pst-optexp} provides some high-level macros to allow very convenient definition of completely new components. The macro \cs{newOptexpDipole} generates all organizing code for a new free-ray component. All you have to do is to define a new `drawing' macro \cs{mycomponent@iii} which contains all drawing code. Analogously \cs{newOptexpDipoleNolabel} defines a new free-ray object without label (like \cs{polarization}) and \cs{newOptexpTripole} defines a new reflective component. New fiber-optical components can be defined using \cs{newOptexpFiberDipole}. This macro differs from its free-ray analogous only in that it presets \parameter{fiber} and hence directly connects the component with its reference nodes. The first node in the parameter list gets connected with a node \nodename{tempNode@A@}, the second node with a node \nodename{tempNode@B@}. These two internal nodes are preset to \paramvalue{(0,0)} and can be overwritten within the drawing macro. The syntax of the macros is \begin{lstlisting} \newOptexpDipole[fixed options]{name}{default options} \newOptexpDipoleNolabel[fixed options]{name}{default options} \newOptexpTripole[fixed options]{name}{default options} \newOptexpFiberDipole[fixed options]{name}{default options} \end{lstlisting} The \texttt{default options} are simply a list of PSTricks parameters which are taken as defaults for the new component. The optional argument allows setting of parameters which cannot be overridden later. This is illustrate a bit more in the next code snippet, which also shows how the coordinate system is handled within the \cs{mycomponent@iii} macro. \medskip \begin{LTXexample}[width=4.5cm] \newOptexpTripole{mygrid}{subgriddiv=5, griddots=0, subgridwidth=\pslinewidth, gridwidth=2\pslinewidth} \makeatletter \def\mygrid@iii{% put here all PSTricks drawing code \psgrid(-1,0)(1,1) }% \makeatother \begin{pspicture}[showgrid=true](4,4) \pnode(0,1){A}\pnode(2,2){G}\pnode(3,0){B} \mygrid[gridcolor=red,labeloffset=1.5](A)(G)(B){myGrid} \psline[style=Beam](A)(G)(B) \end{pspicture} \end{LTXexample} \medskip The default position of the label reference point is (0,0). If you want to change this, you have to define a new pnode named \nodename{tempNode@Label} in the \cs{mycomponent@iii} macro. If you create a new component, please send it to me then I can incorporate this in a new released version. \newpage \section{Examples} \begin{LTXexample}[pos=t,vsep=8mm] \begin{pspicture}(10,2)

But as the topic is rather difficult if you want to do it properly (components should be placed above the beam, but the new nodes are available only when the component is drawn) it could take very long until this feature will be implemented. \end{itemize} \section{Acknowledgements} I thank all the people of the PSTricks mailinglist for the continuous help, especially Herbert Voß. \end{document}
