Creation of topological vortices using Pancharatnam-Berry phase liquid crystal holographic plates |
(a), (b) Micrographs of fabricated LC holographic plates corresponding to Hopf link and Trefoil knot, respectively. The sizes of the pattern areas are both 1 mm×1 mm. (c) Experimental setup for configuring and detecting vortex links and knots. The CCD is fixed on a linear translation stage to implement the scanning of the output field along |
