PHOTON DESIGN SOFTWARE RELEASES (July 2022)

FIMMWAVE Release v7.3

● CAD-like 3D view of FIMMPROP Devices

● FDM Solver: Improved meshing of “IncrementalRIX” shapes in an MWG Waveguide

● FEM Solver: Improved meshing of overlapping shapes in an MWG Waveguide

● FEM Solver: Changed technique for modeling of bend modes by the FEM Solver, to now be rigorous calculation

● FEM and FDM Solvers: Now uses multi-threading for speed improvement

● Various bug fixes

PICWave Release v6.1

● Added support for Photon Design’s Kallistos optimizer module, for automatic optimization of laser/PIC devices

● Mode properties are re-evaluated dynamically in response to carrier-induced refractive index changes in the active region

● New “simple active layer model” for straight gain/EAM/simple modulator sections, which provides a simpler alternative to creating a detailed waveguide cross-section

● Material file upgrades:

- Active material properties can now be defined using analytic functions

- Materials can have local variables which can be used in analytic functions

● Spontaneous emission model now allows separate data for TE and TM polarization

● Various bug-fixes

OmniSim Release 7.3

● FDTD Calculator: CAD-like 3D view for both 2D & 3D models.

● FDTD Calculator: Pre-processing step now faster.
