Hybrid-order Poincaré sphere
Xunong Yi, Yachao Liu, Xiaohui Ling +5
In this work, we develop a hybrid-order Poincaré sphere to describe the evolution of polarization states of wave propagation in inhomogeneous anisotropic media. We extend the orbit…
Photonic spin Hall effect in metasurfaces with rotational symmetry-breaking
Yachao Liu, Xiaohui Ling, Xunong Yi +5
Observation of photonic spin Hall effect (SHE) in dielectric-based metasurfaces with rotational symmetry breaking is presented. We find that the spin-dependent splitting is a uniqu…
Generation of cylindrical vector vortex beams by two cascaded metasurfaces
Xunong Yi, Xiaohui Ling, Zhiyou Zhang +6
We present a simple and efficient method to generate any cylindrical vector vortex (CVV) beams based on two cascaded metasurfaces. The metasurface works as a space-variant Panchrat…
Generation of arbitrary cylindrical vector beams on the higher order Poincare sphere
Shizhen Chen, Xinxing Zhou, Yachao Liu +3
We propose and experimentally demonstrate a novel interferometric approach to generate arbitrary cylindrical vector beams on the higher order Poincare sphere. Our scheme is impleme…
Realization of polarization evolution on higher-order Poincare sphere with metasurface
Yachao Liu, Xiaohui Ling, Xunong Yi +3
We present a simple and convenient method to yield cylindrical vector (CV) beams and realize its polarization evolution on higher-order Poincare sphere based on inhomogeneous biref…
Geometric Photonic Spin Hall Effect with Metapolarization
Xiaohui Ling, Xinxing Zhou, Xunong Yi +2
We develop a geometric photonic spin Hall effect (PSHE) which manifests as spin-dependent shift in momentum space. It originates from an effective space-variant Pancharatnam-Berry…
