We fabricated Nitrides-based THz-QCL structure grown on GaN substrate. The Output power for QCL on GaN substrate showed ten times higher value than that of QCL on MOCVD-GaN template. We for the first time observed THz spontaneous emission spectrum on the Nitrides-based THz-QCL on injection current.
