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

As the market’s leading laser simulator, Harold is equipped to model the diffusion and accumulation of carriers due to forward or reverse bias, the effect this has on a material’s refractive index through the plasma dispersion effect, and find how a supported mode’s effective index changes with applied voltage.

Examples:

• Silicon Modulators

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

Examples:

• AWGs
• Echelle Gratings
