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…

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…
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…
Optimal preselection and postselection in weak measurements for observing photonic spin Hall effect
Xinxing Zhou, Xing Li, Hailu Luo +1
Photonic spin Hall effect (SHE) holds great potential applications in precision metrology. How to obtain a high measurement precision is an important issue to detect the photonic S…
Femtosecond pulse generation from a Topological Insulator mode-locked fiber laser
Hao Liu, Xu-Wu Zheng, Meng Liu +7
We reported on the generation of femtosecond pulse in an anomalous-dispersion fiber ring laser by using a polyvinyl alcohol (PVA)-based Topological Insulator (TI), Bi2Se3 saturable…
