In this article, the spin Hall effect of light (SHEL) on a nanometal film and demonstrate it experimentally via weak measurements was investigated. And the spin-orbit coupling in the SHEL can be effectively modulated by adjusting the thickness of the metal film, and the transverse displacement is sensitive to thickness of metal film in a certain range for horizontal polarization light.Abstract:
We theorize the spin Hall effect of light (SHEL) on a nanometal film and demonstrate it experimentally via weak measurements. A general propagation model to describe the relationship between the spin-orbit coupling and the thickness of the metal film is established. It is revealed that the spin-orbit coupling in the SHEL can be effectively modulated by adjusting the thickness of the metal film, and the transverse displacement is sensitive to the thickness of metal film in a certain range for horizontal polarization light. Importantly, a large negative transverse shift can be observed as a consequence of the combined contribution of the ratio and the phase difference of Fresnel coefficients.read more

Spin-orbit interactions of light
TL;DR: In this paper, the authors provide an overview of the fundamental origins and important applications of the main spin-orbit interaction phenomena in modern optics that play a crucial role at subwavelength scales, including spin-Hall effects in inhomogeneous media and at optical interfaces, spindependent effects in non-paraxial (focused or scattered) fields, spin-controlled shaping of light using anisotropic structured interfaces (metasurfaces).

Identifying graphene layers via spin Hall effect of light
TL;DR: In this article, the spin Hall effect (SHE) of light is used for characterizing the structure parameters variations of nanostructures, and the authors proposed using the SHE of light to identify the graphene layers, based on the mechanism that the transverse displacements in the SHE are sensitive to the variations of graphene layer numbers.
