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…
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…
