Paper Abstract

This paper reviews recent advances in graphene plasmonic heterostructures for new types of terahertz lasers. We theoretically discovered and experimentally manifested that the excitation of surface plasmons in population-inverted graphene by the terahertz photons results in propagating surface plasmon polaritons with a giant gain in a wide terahertz range. Furthermore, double graphene layer heterostructures consisting of a tunnel barrier insulator sandwiched with a pair of gated graphene monolayers are introduced. Photoemission-assisted quantum-mechanical resonant tunneling can be electrically tuned to meet a desired photon energy for lasing, resulting in enormous enhancement of the terahertz gain. Current injection structures are also addressed.
