The Effect of Doping in Split-Well Direct-Phonon THz Quantum-Cascade Laser Structures
We have studied the effect of doping on the temperature performance of a split-well (SW) direct-phonon (DP) terahertz (THz) quantum-cascade laser (QCL) scheme supporting a clean three-level system. Achieving a system that is as close as possible to a clean n-level system proved to be the strategy th...
