+\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 \texttt{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}.

+\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.

+\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.

+\parameter{labelstyle} defines the textstyle that is used to typeset

+\cs{rput}. The parameter \parameter{labelref} sets the reference

+\subsection{Named Objects}\label{sec:namedobj}
+
+\begin{description}
+  \paramitem{compname}{<string>}{\{\}}
+\end{description}
+
+\noindent Every \texttt{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 \texttt{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
+    <compname>ExtNode & Node for external connections (\emph{external node})\\
+    <compname>Intern1 & Node which should be connected to the first reference node. 
+       In the text we refer to this node as \emph{left outer node} \\
+    <compname>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} & \\
+    <compname>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}{<ref string>\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 \texttt{pst-circ}) or a detector to a computer.
+
+\parameter{extnode} controls the position of the additional node and
+takes a \paramvalue{<ref string>} 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{<ref string>} 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}.

+\subsection{Connecting Objects}\label{sec:connecting}

+\begin{description}
+\paramitem{conn}{<conn definition>}{-}
+\item[\param{fiber}:] alias for \parameter{conn=f-f}
+\item[\param{beam}:] alias for \parameter{conn=o-i}
+\end{description}
 
-In the sections \ref{sec:lens}--\ref{sec:custom} the
-available components with their parameters are described. Up to now
-there are two types of components: those which require two reference
-points and do not alter the direction of the passing light beam (for
-example lenses and retardation plates) and those which work in
-reflection and require three reference points (mirrors, grids,
-beamsplitters etc.).
+\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{<conn definition>}.
+
+\begin{table}\centering
+\addtolength{\extrarowheight}{1.5mm}
+\begin{tabularx}{0.8\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{<conn definition>}, their detailed description and scope.}\label{tab:conn}
+\end{table}
+
+The first letter (before the dash) in the \paramvalue{<conn definition>}
+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:styles}).
+
+The way how to really use this kind of connections should become more
+clear after looking at the following examples in this section.
+
+\medskip
 
-In section \ref{sec:general} general parameters are described that are
-not proprietary to a specific unit but can be used for several different
-components. Finally, in section \ref{sec:labels} the options for the
-positioning of labels are explained.
+\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}
 
-The appearence of all components can be changed with the corresponding
-standard PSTricks parameters such as \parameter{fillstyle}
-or \parameter{linestyle}. For some components changing only parts of the
-layout is possible (e.g. the extended part of mirrors). For those cases
-psstyles are provided that influence only the corresponing part of the
-components and can be redefined using \cs{newpsstyle}.
+\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}

+\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, \texttt{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=...]{<from>}{<to>}
+\end{lstlisting}
+
+\medskip
+
+\noindent If \paramvalue{<from>} or \paramvalue{<to>} 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{<from>} object, the other one to
+the \paramvalue{<to>} 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]

+With the help of the \cs{drawbeam} macro we can adapt

+\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.

-The parameter \parameter{angle} is available for the macros \cs{optbox}
-and \cs{crystal} only, as for the most other cases it would make
-no sense. \parameter{optional} can be used with every component and marks it as
-optional and can be configured by changing the psstyle \parameter{OptionalStyle}.
-\parameter{position} is equivalent to the \parameter{npos} parameter of \cs{ncput},
-but is used only for the \lq dipole\rq-macros to position the component
-between the two given points. In addition, there is a parameter
-\parameter{abspos} that allows absolute positioning between the two line
-points. \parameter{showoptdots} shows in black the two points calculated for the
-positioning of the component, and in red the reference points for the
-label.
+Fiber-optical objects are automatically connected to the reference
+nodes. The style of all fiber connections can be configured
+independently (see Sec.~\ref{sec:styles}).
+
+For some components it might me nice to highlight some
+internals. If \parameter{usefiberstyle} is enabled, for examples the
+passing parts of the optical filter are drawn with the \styleshape{Fiber}
+style. In the documentation this parameter is enabled to show the parts
+which would be highlighted.

+
+All these psstyles control the appearence of the fiber parts before and
+after each object. 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.

+\begin{itemize}
+\item Automatic sizing of optboxes (like a \cs{psframebox}
+\item Even more soffisticated beam drawing (draw beam before object contours)
+\item Drawing of extended beams with focusing and so on could be integrated to
 some extent in future versions. 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.
