Abstract :
We predict strong amplification of terahertz radiation by the stimulated generation of plasmons in a planar array of graphene micro/nanocavities. Amplification drastically enhances due to lateral and vertical confinement of the plasmons in graphene micro/nanocavities and superradiant nature of electromagnetic radiation from the array.
