Abstract

Current-injection pumping in graphene makes carrier population inversion enabling lasing and/or amplification of terahertz (THz) radiation. We have recently demonstrated single-mode THz lasing at 100K in graphene-channel transistor laser structures. Introduction of a gated double-graphene-layered (G-DGL) van der Waals heterostructure is a promising route to further increase the operation temperature and radiation intensity via plasmon- and/or photon-assisted quantummechanical tunneling. We have proposed a cascading of the G-DGL unit element working as a new type of THz quantumcascade lasers. Numerical analyses demonstrate further increase of the quantum efficiency of THz lasing by orders of magnitude compared to a transistor or single G-DGL structure.
