GaInAsSb-AlGaAsSb multiple quantum-well (QW) lasers with an emission wavelength of 2.81 μm are reported. The ridge waveguide lasers with highly strained QWs show continuous-wave laser emission up to 25°C; in pulsed mode, the lasers operate up to 60°C. For pulsed operation, a threshold current density of 360 A/cm2 is found for devices with 30-μm stripe width and 2-mm cavity length at room temperature. A low threshold current density at infinite length of 248 A/cm2 is derived.
