Abstract

InGaAs/GaAs strained-layer quantum well (SQW) lasers with low threshold current,¹ high efficiency, and high power,² are suited for fiberoptic transmitters, amplifiers, interconnect, and local-area network applications. There is, however, an important concern with respect to the high temperature operation and reliability of these lasers which would be used in emerging avionic applications. In this paper, we report for the first time on strained-layer lasers capable of high-temperature operation up to 200°C, their high power characteristics, and preliminary reliability data at 70°C and 100°C.
