Abstract :
This paper reviews recent advances in graphene active plasmons toward new types of terahertz lasers. We theoretically discovered and experimentally manifested that the carrier population inversion in graphene results in stimulated emission of plasmons with a giant gain, leading to superradiant terahertz lasing from a structured graphene.
