Research on the performance of the spin Hall effect of light based on a magnetized plasma layered structure

摘要

In this paper, a new, to the best of our knowledge, engineering structure is proposed to explore the sensitivity of the performance of the spin Hall effect of light (SHEL) to external parameters. The structure is composed of a glass layer, air layer, and middle layer, which is made up of a magnetized plasma layered structure. The simulation results show that all of the plasma frequencies, the frequency of incident light, the number of magnetized plasma layers, and the magnetic field distribution do make a difference to the performance of the SHEL. In the calculation process, the transfer matrix method is used to obtain reflection coefficients and then obtains the lateral displacement. The computed results demonstrate that the horizontal displacement of SHEL gets to the largest value when the plasma frequency is quadruple omega(p0), and the horizontal displacement trails off while the turning point veers to the right with the augmentation of the frequency of incident light. Furthermore, the horizontal displacement of SH will suffer from an increasing number of magnetized plasma layers. It is also confirmed that the magnetic field distribution has some effects on the behavior of SHEL. Through these findings, certain parameters can be measured by measuring the angle of shift and the size of the horizontal displacements, such as the refractive index. Thus, our research is of great help to some applications, such as sensors. (C) 2021 Optical Society of America
