Ridge Multiple Quantum Well Laser

laserex07.in : Ridge Multiple Quantum Well Laser

Requires: Blaze/Quantum/Laser
Minimum Versions: Atlas 5.28.1.R

This example demonstrates the simulation of GaAs/AlGaAs ridge laser diode. The ridge structure allows two fundamental modes: TE-like and TM-like, as solved by vector Helmholtz solver. Due to higher TE gain, the TE-like mode dominates. Several slab modes are also present in the active region and contribute to total laser intensity.

The key points of this simulation are :

  • Multi-transverse mode simulation, with mode competition
  • Demonstration of vector Helmholtz solver
  • Demonstration of Newton scheme for coupling of photon rate equations with drift-diffusion transport equations

The results show 2D plots of total optical intensity at anode bias of 1.5V and 3V, with the obvous contribution of non-fundamental modes. The IV log file contains information of the power, photon density modal gain, modal loss and modal refractive indexes for each mode. Spectrum log files contain information on gain and spontaneous emission spectra for each quantum well.
