摘要
Abstract In this paper, by utilizing the transfer matrix method, a structure composed of one-dimensional (1D) periodic multilayer dielectrics, InSb, and nonlinear material is proposed to investigate the behavior of the spin Hall effect of light (SHEL) and its nonreciprocity and bistable features. The results demonstrate that, as the light intensity increases, the reflection coefficients under both TM and TE waves have a bistable phenomenon, and the points of both horizontal and vertical displacements are consistent with the regions where reflection is close to 0. Furthermore, to make our study complete, the thicknesses of the nonlinear and InSb layers are adjusted to study the effects on the performance of SHEL, and it can be found that, with the escalation of the thicknesses of the nonlinear and InSb layers, all the points of displacements are shifting to the direction of the angle. Besides, all parameters demonstrate the phenomenon of nonreciprocity. This research supplies meaningful guidelines for some optical instruments, such as light intensity sensors.
