Tunable Terahertz Amplifier Based on Slow Light Edge Mode in Graphene Plasmonic Crystal

A terahertz (THz) amplifier based on graphene plasmonic crystal is presented in this paper. The amplifier is composed of periodic graphene-silicon arrays, and graphene is used as the THz wave gain medium due to its negative conductivity at a certain temperature and bias voltage. The plasmonic bandga...
