16. Doping Layers in Quantum Cascade Lasers: A study in doping density, position and migration effects
University essay from Lunds universitet/Matematisk fysikAbstract : Quantum Cascade Lasers (QCLs) consist of several semiconductor materi- als sandwiched together. The QCL achieves stimulated emission in the mid-IR (m-IR) to the THz region of the electromagnetic spectrum by inter-subband transitions. These parts of the electromagnetic spectrum are hard to lase in with conventional means. READ MORE
