摘要通过理论上考虑含有石墨烯的介质板，我们研究了石墨烯层对光的自旋霍尔效应（SHEL）的角古斯-汉欣（AGH）位移和横向角位移和空间位移的影响。通过控制外加电压，发现在含有石墨烯的平板的透射共振附近，存在着巨大的可调谐的AGH位移和横向位移（TS），这是由p偏振和偏振波引起的.我们还发现，在垂直入射角附近，在含有石墨烯的界面上，SHEL对偏振和p偏振波都可以产生巨大的可调谐TS。预计这些现象可以导致石墨烯在各种光学器件中的重要有趣和新颖的应用，等等。图形摘要
AbstractBy theoretically considering a dielectric slab containing graphene, we investigate the effect of the graphene layer on the angular Goos-Hänchen (AGH) shifts and the transverse angular and spatial shifts from the spin-Hall effect of light (SHEL) for the reflection of a light beam. Through manipulating the voltage applied to graphene via an exterior gate, it was found that near the transmission resonance of the slab containing graphene, the giant and tunable AGH shifts and transverse shifts (TS) for boths-polarized andp-polarized waves are present. We also find that near the normal incident angle, the giant and tunable TS from SHEL for boths-polarized andp-polarized waves can occur on the interface containing graphene. It is expected that these phenomena can result in significant interesting and novel applications of graphene in all kinds of optical devices, and more.Graphical abstract
