摘要：

GaSb-based 2.4 mu m InGaAsSb/AlGaAsSb type-I quantum-well laser diode is fabricated. The laser is designed consisting of three In0.35Ga0.65As0.1Sb0.9/Al0.35Ga0.65As0.02Sb0.98 quantum wells with 1% compressive strain located in the central part of an undoped Al0.35Ga0.65As0.02Sb0.98 waveguide layer. The output power of the laser with a 50-mu m-wide 1-mm-long cavity is 28 mW, and the threshold current density is 400 A/cm(2) under continuous wave operation mode at room temperature.
