FIMMWAVE/FIMMPROP
Waveguide mode solver / Waveguide propagation simulation software
It has a vector mode solver for waveguide structures, employs numerous complementary algorithms, and can calculate a wide variety of waveguides using arbitrary materials and a highly flexible waveguide CAD tool. Since it can model propagation within optical fibers in 2D/3D structures, it allows for easy simulation of fiber couplers, tapered fibers, lens fibers, fiber Bragg gratings, and more. With user-friendly features backed by years of experience, it enables fast and accurate analysis of optical waveguides and optical fibers.
