How to Convert from RSoft Simulations to Zemax and Back

This tutorial illustrates how to convert information from Zemax into RSoft’s propagation software and back. This can be useful for multi-stage cases in which one part of the system is a bulk optical system, and a waveguide in others. In this example, we will look at the coupling from a focusing lens into a small silica fiber. 

We will first create output information from Zemax and then convert these files into field files that can be used for a BPM propagation. The result will be that Zemax is used to propagate a Gaussian complex amplitude through a bulk optical system, and focus it at the input face of a single mode fiber. The resulting complex amplitude is then imported into RSoft software and propagated through the fiber. The resulting data can then be read back into Zemax if needed.

How to Get Real Waveguide Mode Data Into Zemax

Zemax now supports the input of mode field data from Optiwave's OptiBPM and OptiFiber codes. This makes it easy to improve the accuracy of fiber and waveguide coupler designs using Physical Optics in Zemax, by providing more accurate input data. This article gives several examples.

Understanding paraxial ray tracing

Paraxial rays and parabasal rays are often used in OpticStudio to calculate system data and analysis results. It is important to understand what these rays are in order to avoid confusion in analysis results. This article discusses these special rays and how they differ from each other and from real rays.
