Modeling of high-Q closed mode structures switching dynamics in large rectangular cavities

The results of modeling the laser generation controlled switching between high-Q closed mode structures in large rectangular cavities (up to 1x1mm) based on AlGaAs/InGaAs/GaAs heterostructures are presented. The model is based on rate equations. The basic principle of lasing switching is the controlled change in the internal optical loss due to the quantum-confined Stark effect).
