2.0 µm multiple quantum-wells InGaAsSb/AlGaAsSb laser diode operating continuous wave at room temperature

The multiple quantum wells (MQWs) InGaAsSb/AlGaAsSb laser diodes (LDs) with an emission wavelength around 2.0μm were designed and fabricated by molecular beam epitaxy (MBE). The good performance of LD was achieved, with the low threshold current of 225 mA, and the slope efficiency of 0.23 W/A, respectively. The maximum outpower of 16 mW at 500 mA drive current was obtained at room temperature(RT).
