Suppression of carrier leakage in 4.8 [micrometre] - Emitting quantum cascade lasers
In this work we show that by using both deep quantum wells and tall barriers in the active regions of quantum cascade (QC)-laser structures and by tapering the conduction-band edge of both injector an extractor regions one can significantly reduce the leakage of the injected carriers. Threshold-curr...
