Numerical Simulations of Gain and Power of a Multi-Quantum Well Laser

This paper presents the results and procedures of simulations of our Multi-Quantum Well (MQW) laser in a model constructed in the commercial solvers of the Ansys/Lumerical® software. Usually, the design and fabrication of lasers MQW are challenging and expensive, thus simulations can hasten the development and give insights about design parameters. In this work, simulated power curves are compared to the measured curves, and a good agreement is obtained when the parameters are adjusted. Nonradiative recombinations and self-heating are the main effects that influence the performance of the simulated laser.
