Quantized photonic spin Hall effect in graphene
Liang Cai, Mengxia Liu, Shizhen Chen +4
We examine the photonic spin Hall effect (SHE) in a graphene-substrate system with the presence of external magnetic field. In the quantum Hall regime, we demonstrate that the in-p…
Generation of perfect vortex and vector beams based on Pancharatnam-Berry phase elements
Yachao Liu, Yougang Ke, Junxiao Zhou +4
Perfect vortex beams are the orbital angular momentum (OAM)-carrying beams with fixed annular intensities, which provide a better source of OAM than traditional Laguerre- Gaussian…
Strong spin-orbit interaction of light on the surface of atomically thin crystals
Mengxia Liu, Liang Cai, Shizhen Chen +3
The photonic spin Hall effect (SHE) can be regarded as a direct optical analogy of the SHE in electronic systems where a refractive index gradient plays the role of electric potent…

Realization of tunable spin-dependent splitting in intrinsic photonic spin Hall effect
Xiaohui Ling, Xunong Yi, Xinxing Zhou +4
We report the realization of tunable spin-dependent splitting in intrinsic photonic spin Hall effect. By breaking the rotational symmetry of a cylindrical vector beam, the intrinsi…
Photonic spin Hall effect for precision metrology
Xinxing Zhou, Shizhen Chen, Yachao Liu +2
The photonic spin Hall effect (SHE) is generally believed to be a result of an effective spin-orbit coupling, which describes the mutual influence of the spin (polarization) and th…
