本文研究了平面多层膜结构反射光束的石墨烯辅助Goos-Hannen(GH)漂移。由于石墨烯在可见光范围内具有独特的光学性质，可以通过调整费米能量来调制增加的正Goos-Hancen位移。此外，可以通过改变石墨烯的层数、介质的厚度、入射波长等来调节GH位移。这些结果将有助于设计基于石墨烯的新型光学传感和开关。
In this paper, the graphene-assisted Goos-Hanchen (GH) shift of the optical beam reflected from a planar multilayer configuration is investigated. The increased positive Goos-Hanchen 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.
