WGMODES - Optical Eigenmode Solver for Dielectric Waveguides

Above: Example of optical mode profile calculated with modesolver

Features

Complete, documented source code is provided
Includes scalar, semivectorial and full-vector versions
Full vector version can determine all three field components of both H and E
Supports anisotropic materials, with non-diagonal permittivity matrices
(Caveat: one principal axis must point in z-direction.)
Allows non-uniform mesh sizes (both full-vector and semivectorial)
Incorporates perfectly-matched boundary conditions, using complex coordinate stretching
Provides tools for describing all of the most common rectangular waveguides
Many examples provided

Download

The software and associated utilities are written entirely as MATLAB scripts (m-files). To install, create a directory and unzip all of the files into it. It is recommended that you add this directory and the "tools" subdirectory to your MATLAB path so that you can invoke the modesolver from other directories.
