Abstract

In this work, we optimize the thermal performance of a double quantum well GalnNAs ridge waveguide laser using an accurate in-house 2D electro-opto-thermal laser simulator. The simulator has shown good agreement with experiments after a detailed calibration procedure. Using calibrated material parameters, we investigate the influence of the p-cladding doping concentration on the heat generation within the laser. It is found that due to the competition between Joule and free carrier absorption heating, an optimum p-cladding doping concentration/profile exists.
