LASERMOD - Active Component Tool

LaserMOD

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 processeswithin a self-consistent scheme.

  • 1D, 2D and cylindrical (quasi-3D)
  • Self-consistent solution of optics, quantum mechanical gain, and electro-thermal transport
  • Steady-state and time dependent simulation
  • 8×8 KP band calculation for gain
  • Integrated BPM and FEM mode solvers

Applications : 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 semiconductor materials), Hybrid & Multilevel applications when combined with other tools in the RSoft suite.

Tapered Laser Utility

The Tapered Laser Utility† provides an efficient and accurate design tool for analyzing and optimizing tapered semiconductor laser diodes. It essentially combines, two of RSoft’s most powerful and mature simulation tools BeamPROP and LaserMOD, to provide a full 3D simulation of tapered laser diodes. The quasi-3D electrical, quantum mechanical gain and thermal calculations are performed via LaserMOD, whereas the optical field is propagated via BeamPROP.

  • Self-consistent optical, electronic and thermal simulation.
  • Extensible material libraries.
  • Output information includes L-I curves, I-V curves, spatial field plots, farfields etc.
  • Capable of simulating physical effects like spatial hole burning, filamentation, over pumping etc.

Applications : Tapered laser diode design
