We fabricated terahertz quantum cascade lasers (THz-QCL) using a resonant LO phonon depopulation scheme, which were made of both GaAs/AlGaAs material system and GaSb/AlSb material system. The GaAs/AlGaAs THz-QCL has successfully demonstrated a high peak power ( few tens of milliwatts) operation and a high operating temperature ( 123K). We also report research activities of the THz-QCL in NICT.
