High-power and high-efficiency 1.3 µm InAsP compressively-strained MQW lasers at high temperatures

Abstract
A high output power of 37 mW and high slope efficiency of more than 0.55 W/A at 90°C has been obtained by using 1.05 µm InGaAsP barrier layers with optimised composition for 1.3 µm InAsP compressively-strained MQW laser diodes.
