Author Affiliations +
We have demonstrated room-temperature CW operation of type- II quantum cascade (QC) light emitting diodes at 4.2 micrometers using InAs/InGaSb/InAlSb type-II quantum wells. The type-II QC configuration utilizes sequential multiple photon emissions in a staircase of coupled type-II quantum wells. The device was grown by molecular beam epitaxy on a p-type GaSb substrate and was composed of 20 periods of active regions separated by digitally graded quantum well injection regions. The maximum average output power is about 250 (mu) W at 80 K, and 140 (mu) W at 300 K at a repetition rate of 1 kHz with a duty cycle of 50%.
