FIMMWAVE/FIMMPROP is probably the most widely used propagation tool for the modelling of silicon photonics: rigorous (no slowly varying approximation), fully vectorial, offering wide angle capability and very high design flexibility. The examples below are a selection of applications focusing on silicon photonics.

Examples:

• SOI Waveguides
• Surface Grating
• Planar Taper
• Optical Ring Resonator
• MMI Demultiplexer
• SOI SG-DBR Grating
• Anti-reflection coating

Although FIMMPROP is generally the best method for modelling passive silicon photonics components, FDTD and FETD can also be useful.

Examples:

• Nanowire Optimisation

PICWave and Harold can be used to model a variety of active silicon devices, from hybrid silicon/III-V lasers to QCSE modulators. PICWave can also be used to model active and passive PICs based on silicon or other platforms.

Examples:

• SOI hybrid taper laser
• SOI Hybrid Laser
• EA Modulator (QCSE)
• Large ring resonators

EPIPPROP can model AWGs and echelle gratings in silicon photonics and other high-index platforms.

Examples:

• AWGs
• Echelle Gratings
