Graphene-assisted resonant transmission and enhanced Goos-Hanchen shift in a frustrated total internal reflection configuration

Graphene-assisted resonant transmission and enhanced Goos-Hanchen shift are investigated in a two-prism frustrated total internal reflection configuration. Due to the excitation of surface plasmons induced by graphene in a low terahertz frequency range, there exist the resonant transmission and anomalous Goos-Hanchen shifts in such an optical tunneling configuration. As compared to the case of the quantum well, a graphene sheet with unique optical properties can enhance the resonant transmission with a relatively low loss and modulate the large negative and positive Goos-Hanchen shifts by adjusting the chemical potential or electron relaxation time. These intriguing phenomena may lead to some potential applications in graphene-based electro-optic devices. (C) 2016 Optical Society of America
