We use eight-band k·p energy band structure model to help design novel GaInSb/AlGaInSb mid-infrared multiple quantum well (MQW) structures with an emitting mid-infrared waveband of 4-5 μm. Simulation results suggest that the number of quantum wells has little influence on the spontaneous emission ra...
