Optimization of an optically pumped 1.3-μm GaInNAsvertical-cavity surface-emitting laser

Numerical model predictions are used to optimize the design of an 980-nm-pumped 1.3-μm GaInNAs vertical-cavity surface-emitting laser. The optimum architecture utilizes pumping through the substrate and a double-band mirror to obtain double-pass pumping. We compare the results obtained with this approach to those with conventional architectures. These results are of general relevance to GaInNAs optically pumped surface-emitting or amplifying structures
