TL;DR: In this paper, a simple and efficient method to generate cylindrical vector vortex (CVV) beams based on two cascaded metasurfaces is presented, which can produce any desirable vortex phase and vector polarization.
Journal ArticleDOI
Generation of arbitrary vector vortex beams on hybrid-order Poincaré sphere
TL;DR: In this article, a vector vortex beam can be decomposed into a vector beam and a vortex, whereby the generation can be realized by sequentially using a q-plate and a spiral phase plate.
Journal ArticleDOI
Hybrid-order Poincare sphere
Xunong Yi,Xunong Yi,Yachao Liu,Xiaohui Ling,Xinxing Zhou,Yougang Ke,Hailu Luo,Shuangchun Wen,Dianyuan Fan +8 more
TL;DR: In this article, a hybrid-order Poincar\'e sphere is proposed to describe the evolution of polarization states of wave propagation in inhomogeneous anisotropic media, where the Berry curvature is regarded as an effective magnetic field with monopole centered at the origin of sphere.
