摘要：

Mid-IR (3.8-3.9 mu m) interband cascade lasers based on InAs/GaInSb type-II heterostructures have been demonstrated at temperatures up to 210 K. From several lasers at temperatures above 100 K, we observed a slope greater than 750 mW/A per facet corresponding to a differential external quantum efficiency exceeding 460%. Also, a peak optical output power exceeding 4 W/facet and peak power efficiency of 7% were observed from one laser at 80 K. (C) 1999 American Institute of Physics. [S0003-6951(99)04942-6].
