Photonic spin Hall effect in Haldane model materials [PDF]

open access: greenPhysical Review B, 2023
The photonic spin Hall effect of light beams reflected from the surfaces of various two-dimensional hexagonal crystalline structures, considering their associated time-reversal $\mathcal{T}$ and inversion $\mathcal{I}$ symmetries, is investigated. Employing the Haldane model with tunable parameters as a generic model, we examine the longitudinal and ...

Photonic Spin‐Hall Effect at Generic Interfaces [PDF]

open access: bronzeLaser & 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 ...

Black phosphorus terahertz sensing based on photonic spin Hall effect

open access: goldOptics Express, 2020
A novel terahertz (THz) sensing scheme is proposed based on the photonic spin Hall effect (PSHE). By illumining a paraxial Gaussian THz beam onto a black phosphorus (BP)-based Tamm structure, the reflected beam will undergo in-plane spin splitting, i.e., the centroids of two opposite spin components separate spatially.

Photonic spin Hall effect in hyperbolic metamaterials at visible wavelengths [PDF]

open access: bronzeOptics Letters, 2018
The photonic spin Hall effect in transmission is a transverse beam shift of the out-coming beam depending on polarization of the incoming beam. The effect can be significantly enhanced by materials with high anisotropy. We report, to the best of our knowledge, the first experimental demonstration of the photonic spin Hall effect in a multilayer ...

Coherent control of photonic spin Hall effect in a cavity

open access: goldOptics Express
This paper theoretically investigates the manipulation of the photonic spin Hall effect (photonic SHE) using a four-level closed coherent control coupling scheme in a cavity. The atomic system is configured to function as a combined Tripod and Lambda (CTL), Lambda Λ, and N-level model by properly adjusting the control field strengths and their relative
