摘要：
An optical output power exceeding 210 mW has been achieved using 1.625-mu m strained multiple quantum well lasers at a forward current of 800 mA under pulsed operation. We introduced tensile-strained barrier layers to increase internal quantum efficiency. High quantum efficiency is attributed to improved of hole injection efficiency and suppressed electron overflow from wells. The 1.625-mu m high-power lasers are expected to be applied to optical time-domain reflectometers, which enable regular communication light to be used.
