Numerical study of the influence of thermooptic effects on the competition of modes in diode lasers

Year: 2008

Type: article

Abstract: A software package is developed for numerical analysis of radiation of edge-emitting diode lasers. The optical block of the package uses the three-dimensional diffraction method of counterpropagating beams. The current carrier density distribution in a quantum well is found from the diffusion equation, and the temperature distribution is found from the heat conduction equation. The software package can be used to analyse the competition of optical modes and to find the critical current at which single-mode lasing is quenched. The operation of a semiconductor laser having a built-in system of waveguides with antiresonance reflection is analysed. The conditions of single-mode generation with the output power above 1 W are found for this laser.
