High efficiency 1.3 /spl mu/m strained multi-quantum well lasers entirely grown by MOVPE for passive optical network use

A high efficiency of 0.4 W/A at 85/spl deg/C, the highest ever reported for InGaAsP MQW-LDs entirely grown by MOVPE, was realized. The efficiency change was a low 2.5 dB over -40 to +85/spl deg/C for a surface-mount module.
