Abstract
Above room-temperature operation of lambda about 5 µm quantum cascade lasers with three different active regions is reported. Comparison between the three different designs, namely the conventional design, the adoption of blocking barriers into the active region, and the adoption of strain-compensated active regions, is presented.
