摘要
We describe room-temperature 2.78 μm AlGaAsSb/InGaAsSb multiquantum well lasers. Pulsed laser operation was observed at 15°C with a threshold current of 1.1 A (10kA/cm2), and a maximum power output of 30 mW, and a maximum differential quantum efficiency of 9%. Lasers operated pulsed up to 60°C with a characteristic temperature of 58 K over the range of 0-40°C. To date, 2.78 μm is the longest emission wavelength for a room-temperature III-V laser.© 1995 American Institute of Physics.
