Arbitrary cylindrical vector beam generation enabled by polarization-selective Gouy phase shifter
Fig. 1. (a) Basic Poincaré sphere. Selected points a1–a6 on the surface include polarization states from linear polarization to elliptical polarization. (b) First-order HOPS. Selected points b1–b6 represent six CVBs on the surface.
Fig. 2. (a) Fabrication of polarization-selective cylindrical lens. (b) PGPS, which contains two symmetric polarization-selective cylindrical lenses and operates on LCP only. (c) Gouy phases accumulated by PGPS for modes with different indices
