Applications

  • FP Quantum Well lasers
  • Ridge waveguide lasers
  • SOI hybrid lasers
  • VCSELs

Examples

VSCEL Module
The VCSEL Module allows the calculation of multiple optical cavity modes, electrical drift diffusion, heat flow, and electron-photon interactions in a full 3D model.

Building on Photon Design’s decades of experience the VCSEL module provides a fully integrated design environment for the variety of the VCSEL types being used today, including QW materials, current blocking apertures, and more.
