Experimental control of optical helicity in nanophotonics

Tischler, Nora; Fernandez-Corbaton, Ivan; Zambrana-Puyalto, Xavier; Minovich, Aliaksandr; Vidal, Xavier; Juan, Mathieu; Molina-Terriza, Gabriel


An analysis of light-matter interactions based on symmetries can provide valuable insight, particularly because it reveals which quantities are conserved and which ones can be transformed within a physical system. In this context, helicity can be a useful addition to more commonly considered observables such as angular momentum. The question arises how to treat helicity, the projection of the total angular momentum onto the linear momentum direction, in practical experiments. In this paper, we...[Show more]
