Abstract

We experimentally demonstrate terahertz light amplification by instability-driven stimulated emission of graphene plasmon polaritons in an asymmetric dual-grating-gate transistor structure. D.C. channel current driven by the drain bias voltage induces plasmon instability, alternating the electromagnetic response from the resonant absorption to the resonant amplification (up to 9 % gain) beyond the threshold drain bias voltage at room temperature.
