Abstract

Extremely low-threshold, single-longitudinal-mode operation is reported for 1.5μm band Gain As multiple quantum well, distributed feedback laser diodes. A 5.5 mA minimum threshold current as well as 40 mW maximum light output power and 0–33 W/A maximum quantum efficiency have been attained under CW condition at room temperature.
