In this paper, the graphene-assisted Goos–Hänchen (GH) shift of the optical beam reflected from a planar multilayer configuration is investigated. The increased positive Goos–Hänchen shifts can be modulated by adjusting the Fermi energy due to graphene with unique optical properties in the visible light range. Moreover, the GH shift can be tuned by varying the layers of graphene, the thickness of the medium, incident wavelength, and so on. These results will be useful for designing the novel graphene-based optical sensing and switching.

可见光范围内平面多层配置中石墨烯辅助的Goos–Hänchen位移

在本文中，研究了从平面多层结构反射的光束的石墨烯辅助的Goos–Hänchen（GH）位移。由于石墨烯在可见光范围内具有独特的光学特性，可以通过调节费米能量来调节增加的正Goos–Hänchen频移。而且，可以通过改变石墨烯的层数，介质的厚度，入射波长等来调整GH偏移。这些结果对于设计新颖的基于石墨烯的光学传感和开关将是有用的。
