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. Indexing terms: Semiconductor lasers, Optical communications, LEDs.
