Photonic Spin Hall Effect at Metasurfaces

Science, 2013
Photonic Spin Hall Effect When charged carriers move in a magnetic field, they are deflected—an effect known as the Hall effect. Electrons possess charge and spin, a property related to magnetism. The symmetry of electromagnetism then allows for a spin Hall effect whereby the spin is deflected by an electric field.

Photonic Spin‐Hall Effect at Generic Interfaces

Laser and Photonics Reviews, 2023
AbstractAlthough the photonic spin‐Hall effect (PSHE) at optical interfaces has been widely studied in past years, its physical origin remains obscure. Here, through studying the scatterings of circularly polarized beams obliquely incident on a series of junctions linking two homogenous optical media, how the physical origin of the PSHE evolves as the ...

Optical analogue of the spin Hall effect in a photonic cavity

Optics Letters, 2011
We observe anisotropy in the polarization flux generated in a GaAs/AlAs photonic cavity by optical illumination, equivalent to spin currents in strongly coupled microcavities. Polarization rotation of the scattered photons around the Rayleigh ring is due to the TE-TM splitting of the cavity mode.

Photonic Spin Hall Effect with Nearly 100% Efficiency

Advanced Optical Materials, 2015
Photonic spin Hall effect (PSHE; i.e., spin‐polarized photons can be laterally separated in transportation) gains increasing attention from both science and technology, but available mechanisms either require bulky systems or exhibit very low efficiencies.

Spin Hall Effect of Nonlinear Photons

Laser & Photonics Reviews, 2023
AbstractPhotonic spin Hall effect (SHE) refers to the transverse separation of spin photons in refraction and reflection phenomena. The photonic SHE has been investigated in various optical systems including air–glass interfaces, interfaces containing 2D materials, random media, etc. Here, the spin–orbit coupling (SOC) in nonlinear uniaxial crystals is

Photonic spin Hall effect in twisted bilayer graphene

Journal of the Optical Society of America A, 2021
Here, we investigate the photonic spin Hall effect in twisted bilayer graphene. The optical conductivities for several rotation angles of twisted bilayer graphene are calculated by first principles, based on which a theoretical framework is established to describe the light–matter interaction.
