Optical gain performance of InP based “W” structure with InGaAs(N)/GaAsSb type-II quantum wells are investigated theoretically. The band structure was calculated by using k.p model, taking into account the conduction band mixing with N resonant band, valence band mixing, as well as strain effect. Our studies show that these type-II quantum wells are suitable for mid-infrared (2–4 μm) operation at room temperature.
