Additional Modules for FIMMWAVE
The FIMMWAVE base module includes the real FMM Solver, real FDM Solver, and real Effective Index Solver, along with the SMF and Gaussian Fiber Solvers. Beyond the base module, you can select from a wide variety of add-ons:
FIMMPROP
FIMMPROP is a 3D propagation tool utilizing EigenMode Expansion (EME).
MT-FIMMPROP
The Multi-Topology (MT)-FIMMPROP extension enhances FIMMPROP by creating a layout environment that seamlessly connects multiple FIMMPROP simulations, enabling the simulation of entire PIC components.
Complex Engine
This add-on unlocks the complex versions of all mode solvers, allowing for the analysis of metallic structures and the inclusion of gain and absorption in devices. It also supports PMLs for modeling leaky modes and computing loss in bend modes. When combined with the FIMMPROP module, these features are integrated into FIMMPROP simulations, with PMLs enabling radiation absorption at sidewalls.
FEM Solver
A finite element mode solver is available as an additional module.
Cylindrical Solvers
Fully vectorial and semi-vectorial cylindrical waveguide mode solvers designed for high-performance fiber analysis and other cylindrically symmetric applications.
Kallistos
An advanced automatic optimization tool that enhances the design of photonic devices with minimal user intervention.
Electro-Optic Solver (part of the Thermal/EO Module)
This solver incorporates electro-optic effects into simulations, such as those caused by applied electrodes, including electro-optic modulators in materials like LiNbO3.
Thermo-Optic Solver (part of the Thermal/EO Module)
Enables the study of heater effects or waveguide self-heating, featuring a 2D Poisson Solver to model heat flow in the XY plane. Contact us for more details.
Stress Solver
Models the impact of stress on waveguides and the resulting changes in modes, including thermally induced stress fields.
