Abstract

We designed and fabricated InP-based high electron mobility transistors featuring an asymmetric chirped dual-grating-gate structure with a resonant-enhanced photonic vertical cavity. The device structure greatly enhances the Doppler-effect-driven plasma instability, resulting in intense monochromatic superradiant terahertz emission at 3.55 THz at 140K for the first time. OCIS codes: (040.2235) Far infrared or terahertz; (250.5403) Plasmonics; (270.5580) Quantum electrodynamics.
