We introduce a so-called “split-well direct-phonon” active region design for terahertz quantum cascade lasers (THz-QCLs). Lasers based on this scheme profit from both elimination of high-lying parasitic bound states and resonant-depopulation of the lower laser level. Negative differential resistance is observed at room temperature, which indicates that each module behaves as a clean 3-level system. This study further uses this design to investigate the impact of temperature on the dephasing time of GaAs/AlGaAs THz-QCLs.
