LaserMOD Product Overview

LaserMOD™ is a photonic device design software tool for simulating the optical, electronic, and thermal properties of semiconductor lasers and similar active devices. In these devices, thermal flux and carrier transport can strongly affect overall performance through spatial hole burning and self-heating. LaserMOD accounts for these and other important processes within a self-consistent scheme.


  • Versatile, user-friendly, parametric CAD interface.
  • All simulation modules included in a single package.
  • Integrated with RSoft passive device and system tools.


LaserMOD applications include the following device families:

  • Edge emitting lasers, such as Fabry-Perot (FP), Distributed Feedback (DFB), and Distributed Bragg Reflector (DBR)
  • Cylindrical Vertical Cavity Surface Emitting Lasers (VCSEL)
  • Silicon modulators (Electro-absorptive, electro-refractive, and thermo-optic modulators in silicon and other semi-conductor materials)
  • Hybrid & Multilevel applications when combined with other tools in the RSoft suite


  • 1D, 2D and cylindrical (quasi-3D)
  • Advanced physics based models
  • Self-consistent simulation
  • Steady-state and time dependent simulation
  • 8x8 KP band calculation for gain
  • Integrated BPM and FEM mode solvers
  • Integrated mesh generator
  • Extensible material libraries
  • Tutorial examples
  • On-line help
  • Standard and custom plot generation
