Mode Solvers for Optical Waveguides

FIMMWAVE waveguide mode solvers

FIMMWAVE supports a number of different and complementary mode solvers, each adapted and optimised to solve certain types of waveguide geometries. All the mode solvers are compatible with FIMMPROP, our innovative EigenMode-Expansion propagation tool.

The solvers implemented in FIMMWAVE are:

FMM Solver

Film Mode Matching solver

FDM Solver

A finite difference mode solver

FEM Solver

A finite element mode solver

Eff. Index

The Effective Index Mode Solver

Fibre Solvers

The Fiber Mode Solvers (Cylindrical Solvers)

Complex versions are available for most solvers, allowing losses and even metals to be modelled.

Bend modes can be calculated using the FMM, FDM and FEM Solvers with the Complex Engine.
