Mode Solvers
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.
