Abstract:Abstract. We analyze the efficiency of different materials used for spin-to-orbit angular momentum conversion by applying bending to parallelepiped-shaped bars made of crystals or glasses. It is found that generation of pure screw dislocations of the light wave front with the bending technique is possible only in isotropic materials and crystals belonging to hexagonal and trigonal symmetries, with exception of crystals of the point symmetry groups 3, 3 , 6, 6 and 6/m. We demonstrate that lexan is the most effi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
