摘　　要：GaSb-based 2.4μm InGaAsSb/AIGaAsSb type-I quantum-well laser diode is fabricated. The laser is designed consisting of three In0.35 Ga0.65As0.1Sb0.9/Al0.35 Ga0.65 As0.02Sb0.98 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-μm-wide i-ram-long cavity is 28roW, and the threshold current density is 400A/cm2 under continuous wave operation mode at room temperature.GaSb-based 2.4μm InGaAsSb/AIGaAsSb type-I quantum-well laser diode is fabricated.
