“…Since then, a lot of investigations on SHEL have been carried out at air-glass interface [30]- [36]. IF spatial shift of Gaussian beam reflected from an air-prism interface at the Brewster angle was studied and discussed [37], and some new spin-dependent splitting phenomena, such as spin angular-splitting [38], scattering-related spin-splitting [39] and asymmetric spin-splitting [40], [41], were discovered. In recent years, some researchers have begun to study the transaction properties by considering the SHEL and IPSSL simultaneously.…”

We investigate the spin-dependent splitting systematically by considering spin Hall effect of light and in-plane spin separation of light simultaneously, when a Gaussian beam is reflected from an air-glass interface. It is revealed that there exhibits a spindependent splitting rotation with the increase of the polarization angle, and the rotation direction and speed can be controlled by the incident angle. Remarkably, with the polarization angle increasing from 0 • to 90 • , the splitting rotates 180 • clockwise in total when the incident angle is less than Brewster angle, whereas it rotates an angle under 90 • counterclockwise first and then clockwise return to the original position when the incident angle is larger than Brewster angle. Their initial rotation speeds of splitting to x r direction both become larger as the incident angle approaches to Brewster angle, therefore when the incident angle is equal to Brewster angle, the splitting only forms a 90 • clockwise rotation. These general laws of spin-dependent splitting rotation are demonstrated by instances, and the rotation behaviors are considered as a result of various proportions of transverse spin separation and in-plane spin separation. This research provides a feasible way to manipulate the photon spin in optical nanodevice.

The intriguing photonic spin Hall effect (PSHE) of reflected Laguerre-Gaussian (LG) beams can be exhibited on the systems with optical anti-parity-time (Anti-PT) symmetry. During the reflection, the left/right circularly polarized (LCP/RCP) components of reflected LG beams are considered. By controlling parameters of the Anti-PT systems, the PSHE of reflected LCP/RCP can be identical and symmetrical with respect to incident-reflected plane (IRP). Due to gain/non-Hermitian effects of designed Anti-PT systems, special PSHE near the strong gain points (SGP) and exceptional points (EPs) can be obtained simulatively. Through analyses in PSHE of reflected LCP on four similar Anti-PT systems, specific conclusions that can even be extended to more general cases. Moreover, simulations of PSHE by simultaneously varying the incident angles * and imaginary/real dielectric constants Im/Re[ε] of the Anti-PT systems, specal PSHE and other novel optical phenomena with real applications can be revealed. So Anti-PT systems not only provide novel ways to regulate the PSHE of reflected LG beams, but also offer possibilities for new optical characteristics of devices.
