摘要：

We report improved high-temperature characteristics for In0.2Ga0.8As strained-quantum-well ridge waveguide lasers with an optimized cavity design. We have fabricated In0.2Ga0.8As lasers that operate CW at up to 220-degrees-C with over 9 mW output power. At 200-degrees-C the threshold current is as low as 15.9 mA for a 400 mum long laser with 35/98% reflectivity facets. Optimization of the laser cavity also improves the high-temperature operation of quantum-well lasers in other material systems; we have fabricated GaAs quantum well lasers that operate at up to 220-degrees-C CW.
