Paper Abstract

Room temperature III-nitride QCL THz is reported. With increasing carrier concentration, the peak in optical shifts towards higher energies. Peak in the optical gain increases with carrier concentration demonstrating a blue shift correlated to quantum confinement. THz power increases linearly with current demonstrating an output power of 0.4448 μW at 6THz. A higher THz power is obtained in AlxGa1-xN/GaN/AlxGa1-x heterostructures as compared to heterostructures incorporating In. An increase in the Al-mole fraction results in higher THz power.
