Fimmwave Software

FIMMWAVE Software is a generic, robust, fully vectorial mode finder for 3D waveguide structures, which may be of almost any geometry, such as SOI, polymer, etched GaAs/AlGaAs waveguides, diffused LiNbO3 as well as single and multicore fibres. It contains a variety of robust and computationally efficient solvers optimized for either generic rectangular structures often encountered in opto-electronics or circular fibres with generic refractive index profiles.

The solvers currently implemented in FIMMWAVE are: The FMM Solver, Bend Mode Solver, FEM Solver, Effective Index Solver, General Fibre Solver, Gaussian Mode Fibre Solver etc.

The Molab (mode list auto builder) is a sophisticated algorithm for finding of eigen modes.

Mode Analysis: The following data is available for each mode: confinement factor, overlap integral with material loss profile of waveguide, effective index and propagation constant, dispersion and group velocity, effective mode area.

Parameter Scanners: These routines will allow you to rapidly generate design curves of almost any calculated parameter as a function of almost any input parameter or dimension.

Thermal/EO Module: This includes a 2D Poisson Solver for studying the response of your waveguides to thermal and electrostatic fields. Applications include thermo-optic and electro-optic switch design.
