摘要:
Extremely low-threshold, single-longitudinal-mode operation is reported for 1.5 μm band GaInAs 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.
