We predict the spatial and angular Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts in partial (PR) and total internal reflection (TIR) conditions for fundamental Gaussian mode beams of a wide range of wavelength (400–1300 nm) impinging upon a graphene-coated dielectric surface. The GH and IF shifts turn out to be extremely dependent upon the chemical potential of graphene along with the wavelength of the incident light, thus enabling one to appropriately choose the operating wavelength and tune the chemical potential in the desired region to obtain maximum beam shifts in graphene. We also show that the typical features of the optical beam shifts are potentially linked with the optical conductivity of single-layer graphene. We expect the current study to be of fundamental significance in the field of optoelectronics and device industry based on graphene and other 2D materials.

我们预测了波长范围较大（400-1300 nm）的基本高斯模光束在部分（PR）和全内反射（TIR）条件下的空间和角Goos-Hänchen（GH）和Imbert-Fedorov（IF）位移撞击在石墨烯涂层的介电表面上。事实证明，GH和IF偏移非常依赖于石墨烯的化学势以及入射光的波长，因此使人们能够适当地选择工作波长并调整所需区域中的化学势以获得最大的光束偏移。石墨烯。我们还表明，光束位移的典型特征可能与单层石墨烯的光导率有关。
