摘要：

The spin Hall effect (SHE) of light in layered nanostructures is investigated theoretically in this paper. A general propagation model describing the spin-dependent transverse splitting of wave packets in the SHE of light is established from the viewpoint of classical electrodynamics. We show that the transverse displacement of the wave-packet centroid can be tuned to either a negative or a positive value, or even zero, by just adjusting the structure parameters, suggesting that the SHE of light in layered nanostructures can be enhanced or suppressed in a desired way. The inherent physics behind this interesting phenomenon is attributed to the optical Fabry-Perot resonance. We believe that these findings will open the possibility for developing new nanophotonic devices.
