PICWave and Harold offer a highly effective combination for modelling active devices: Harold allows you to simulate the physics of the hetero-structure, and PICWave can include this model into a larger circuit, allowing you to model any type of laser geometry.

Examples:

• High Power FP Laser
• Mode hopping
• SOI Hybrid Laser
• SOI hybrid taper laser
• SOA
• VCSEL Module
• Mode-locked laser
• DFB EML
• SG-DBR tuneable laser

FIMMPROP is an ideal tool for modelling the passive optical properties of VCSELs e.g. detecting the resonant wavelengths, the field and mode distribution of the cavity modes and the losses. The VCSELs can be cylindrically symmetric or arbitrary in shape and FIMMPROP can model optical external feedback e.g. VCSELs laterally coupled to slow light waveguides.

Examples:

• Laser Cavity Modes

You can use our Active FDTD tool for modelling laser structures with unusual laser geometries, for instance laser nano-rods or photonic crystal lasers.
