Robust optical delay lines via topological protection [PDF]

, 2011
Phenomena associated with topological properties of physical systems are naturally robust against perturbations. This robustness is exemplified by quantized conductance and edge state transport in the quantum Hall and quantum spin Hall effects.

Impact of Polarization Phase of Incident Light on In-Plane Spin Splitting of Reflected Beam

IEEE Photonics Journal, 2022
In this paper, a physical model is established to reveal the relationship between polarization phase of incident light and in-plane spin splitting (IPSS) of reflected beam, and the impact of polarization phase on the IPSS is systematically investigated ...

Unidirectional propagation of the Bloch surface wave excited by the spinning magnetic dipole in two-dimensional photonic crystal slab

Scientific Reports, 2021
The photonic spin Hall effect (PSHE) can be realized in a photonic crystal (PC) slab, that is, the unidirectional Bloch surface wave can propagate along the surface of the PC slab under the excitation of elliptical polarized magnetic dipole.

Controlling photonic spin Hall effect in graphene-dielectric structure by optical pumping

New Journal of Physics, 2020
The photonic spin Hall effect (SHE) provides an effective way to manipulate the spin-polarized photons. However, the spin-dependent splitting is very tiny due to the weak spin–orbit coupling, and previous investigations for enhancing this phenomenon have

Giant Photonic Spin Hall Effect by Anisotropic Band in Photonic Crystal Slabs

IEEE Photonics Journal, 2022
When a paraxial light beam is reflected from/ transmitted through an optical element with rotation symmetry, a tiny small incident angle can arise wave-vector-varying Pancharatnam-Berry (PB) phases, resulting in high-performance photonic spin Hall

Advances in Synthetic Gauge Fields for Light Through Dynamic Modulation [PDF]

, 2018
Photons are weak particles that do not directly couple to magnetic fields. However, it is possible to generate a photonic gauge field by breaking reciprocity such that the phase of light depends on its direction of propagation.
