High order plasmonic vortex generation based on spiral nanoslits

High order plasmonic vortex generation based on spiral nanoslits

Highly localized plasmonic vortices carrying orbital angular momentum are of importance for many applications. Yet, it is a challenge to generating plasmonic vortex with a high topological charge because of no available technique. Here, a novel plasmonic vortex generator is proposed based on spiral...
