Abstract
We report on the continuous wave (cw) operation of AlGaAs single-quantum-well (SQW) lasers grown at a low temperature (375 °C) by molecular-beam epitaxy (MBE). The threshold current and the differential quantum efficiency of the ridge-waveguide laser were 10 mA and 82%, respectively. During the life test, no obvious degradation was observed beyond 2300 h under 8 mW cw operation at 50 °C. The cw operation of SQW lasers grown at low temperatures was achieved by the long baking of the MBE system and the reduction of the V/III flux ratio.
