Abstract

We present a quantum-cascade emitter in the galliumarsenide/aluminum-galliumarsenide (GaAs/AlGaAs) heterosystem whose emission properties are controlled by an additional electric field perpendicular to the transport direction. In our case, the additional field is established by remote delta-silicon doping, which is also responsible for charge carrier supply. The field originating from the ...
