【摘要】 本文报道,极低阈值电流脊形波导~0.85μmGaAs/AsGaAsGRIN-SCHSQW激光二极管优化设计、器件制备和特性.获得了2.2~4mA的极低阈值电流和~0.6mW/mA的微分量子效率.70℃,3mW恒功率寿命试验,推测器件平均工作寿命大于4万小时.

【Abstract】 In this paper, we report the optimal design device fabrication and characteristics for extremely low threshold current ~0. 85μm GaAs/AlGaAs single quantum well Laser diodes with ridge waveguide and graded refractive index separated confinement structures. The extremely low threshold current of 2. 2~4mA and the differential quantum efficiency of ~0. 6mW/mA are obtained. the speed ageing tests are performed under the 70℃ and 3mW. The average lifetime at room temperature is evaluated over 40,000 h.PACC: 4255PReceived 12 September 1996, revised manuscript received 11 November 1996
