摘要
Abstract
At the subwavelength scale,the spin-orbit interaction has a strong influence on basic optical processes and is an important physical effect in micro-and nanoscale optics.The spin Hall effect of light can directly reflect the strength of the spin-orbit interaction,thus receiving extensive research and attention.The spin Hall effect of ordinary light is usually weak,and needs to be measured using weak measurement techniques,which seriously limits the application of the spin Hall effect of light.The spin Hall effect of light generated by a Gaussian beam incident on a half-infinite MoO3 super surface with a grating structure as the substrate is studied.The addition of the super surface greatly enhances the spin Hall effect of light,showing strong tunability.Furthermore,the light beams of different spin components appear to be directed transferred at the surface of the structure,thereby causing the reflectance of one spin component to approach zero,resulting in an asymmetric photon spin Hall effect.The research provides important theoretical support for the application of the photon spin Hall effect in precision detection,optical field control,optical simulation calculation,and microscopic imaging.关键词
