The spin Hall effect (SHE) of light, as an analogue of the SHE in electronic systems, is a promising candidate for investigating the SHE in semiconductor spintronics/valleytronics, high-energy physics and condensed matter physics, owing to their similar topological nature in the spin-orbit interaction. The SHE of light exhibits unique potential for exploring the physical properties of nanostructures, such as determining the optical thickness, and the material properties of metallic and magnetic thin films and even atomically thin two-dimensional materials. More importantly, it opens a possible pathway for controlling the spin states of photons and developing next-generation photonic spin Hall devices as a fundamental constituent of the emerging spinoptics. In this review, based on the viewpoint of the geometric phase gradient, we give a detailed presentation of the recent advances in the SHE of light and its applications in precision metrology and future spin-based photonics.

“…Conventionally, the IF shift is defined as the transverse displacement of the gravity center of the entire reflected light beam, when a left circularly polarized (LCP) or a right circularly polarized (RCP) beam is incident; while SHEL is the transverse splitting of the LCP and RCP spin components when a linearly polarized light (LCP+RCP) is incident. Owing to the potential applications in quantum information and precision metrology, extensive studies on these beam shifts have been carried out both theoretically and experimentally in the past decades, using various materials [16][17][18][19][20][21][22] and different beam shapes [23][24][25]. For an incident linear polarization, no matter what the angle of polarization of the electric field is, the incident light can be always regarded as the superposition of an equal amount of LCP and RCP spin components.…”

In the spin Hall effect of light (SHEL) with an incident linear polarization, the left circularly polarized (LCP) and the right circularly polarized (RCP) spin components are transversely shifted to opposite sides of the incident plane. We find that each spin component of the reflected or the refracted light is actually the coherent superposition of a pair with the same handedness. The two parts in a pair are generated by both the incident LCP and RCP components, respectively, and have different transverse shifts. Their weighted shifts lead to the overall displacement of the corresponding spin component. This perspective can successfully elucidate the dependence of the SHEL spin separations on the angle of polarization of the incident electric field.

“…Goos-Hänchen shift [10,11] and the Pancharatnam-Berry phase [12]. Also, they boost up experimental investigations of SHE of light in a variety of different optical systems [13][14][15][16][17][18][19][20][21][22][23] and the other general spin-dependent transportation phenomena [24][25][26][27][28]. In particular, Hosten and Kwiat identified the connection between the optical SHE of photons and classical light and proposed the "weak measurement" method for attaining ultrahigh sensitivity to angstrom-scale displacements [13].…”

Optics naturally provides us with some powerful mathematical operations. Here, we experimentally demonstrate that during reflection or refraction at a single optical planar interface, the optical computing of spatial differentiation can be realized by analyzing specific orthogonal polarization states of light. We show that the spatial differentiation is intrinsically due to the spin Hall effect of light and generally accompanies light reflection and refraction at any planar interface, regardless of material composition or incident angles. The proposed spin-optical method takes advantages of a simple and common structure to enable vectorialfield computation and perform edge detection for ultrafast image processing.
