在双棱镜阻挫全内反射结构中研究了石墨烯辅助的共振透射和增强的古斯-汉臣位移。由于石墨烯在低太赫兹频率范围内诱导的表面等离子体激元的激发，在这种光学隧穿结构中存在共振透射和反常的古斯-汉臣位移。与量子阱的情况相比，具有独特光学性质的石墨烯片可以以相对低的损耗增强共振传输，并通过调节化学势或电子弛豫时间来调制大的负和正古斯-汉臣位移。这些有趣的现象可能导致石墨烯基电光器件的一些潜在的应用。(C)2016美国光学学会
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
