We have developed THz quantum-cascade lasers based on resonant-phonon-assisted depopulation and using metal-metal waveguides for mode confinement. The band diagram of the QCL structure is illustrated. Based on the combination of these two unique features, many THz QCLs with record performance, including a maximum pulsed operating temperature at 147 K, a maximum cw operating temperature at 97 K were developed.
