Controllable photonic spin hall effect of bilayer graphene

Nanotechnology, 2022
Abstract Bilayer graphene, composed of two layers of monolayer graphene in AB stacking order, has emerged as an alternative platform for atomically thin plasmonic and optoelectronic devices. However, its behavior of photonic spin hall effect remains largely unexplored.

The photonic spin Hall effect sensor

Applied Optical Metrology II, 2017
In this paper, we present an alternative refractive index sensing scheme based on the photonic spin Hall effect (PSHE). We find that the spin splitting induced by the PSHE shows high sensitivity to the refractive index change (RIC) around the Brewster angle.The refractive index of sample is estimated with a precision of the order of 10 −5 refractive ...

Role of in-plane shift in reconstructing the photonic spin Hall effect

Optics Letters, 2022
The photonic spin Hall effect (SHE) manifests itself as in-plane and transverse spin-dependent shifts of left- and right-handed circularly polarized (LCP, RCP) components and originates from the spin–orbit interaction (SOI) of light, where extrinsic orbital angular momentum (EOAM) can induce these shifts.

Photonic spin Hall effect in twisted bilayer phosphorene

Journal of Applied Physics, 2023
We investigate the photonic spin Hall effect of a linearly polarized Gaussian beam reflected on the surface of twisted bilayer phosphorene. The photonic spin shift depends strongly on optical resonance behavior, which is determined by the twist angle. The magnified spin shift near the Brewster angle is sensitive to the twist angle and can be fitted by ...

On-demand customization of the enhancement of the photonic spin Hall effect

Optics Letters
The photonic spin Hall effect (PSHE) has been widely researched, exhibiting great potential in applications of precision measurement, nanophotonic devices, and quantum information processing. However, the enhancement of PSHE in previous work occurs only in the case of limited incident angle, wavelength, and polarization, hence saying nothing of on ...

Photonic spin Hall effect in PT symmetric metamaterials

Frontiers of Physics, 2019
We proposed and demonstrated that PT symmetric metamaterials could be used to achieve enhanced spin Hall effect (SHE) of light. We find that when laser mode is excited in PT symmetric system, the enhanced SHE could be obtained in both transmitted and reflected beams. In addition, as exceptional points (EPs) of PT symmetric system can happen for both p-

Observation of the spin Hall effect of light by a single-photon detector

Optics Letters
We use a single-photon detector to detect the spin Hall effect of light (SHEL) of a quasi-single-photon beam obtained in this Letter. The physics of the spin Hall effect and its quantum weak measurement method with a dimensionless pointer are elucidated through particle number representation.

Photonic spin-Hall effect at the nonparaxial focus of vortex beams

Optics Letters
The spin-dependent transverse deflection of a light beam’s trajectory, due to symmetry breaking of its intrinsic angular momentum structure, is known as the photonic spin Hall effect (PSHE). We propose and demonstrate an optical retroreflection scheme to measure the PSHE at the nonparaxial focus of linearly polarized vortex beam.
