Abstract

We propose a conceptually novel scheme for generation and beaming of optical angular momentum using plasmonic multilayer nanostructure We calculate the optical modes generated by the structure in near and far-field. Our proposed structure architecture, consisting of a plasmonic vortex lens is shown to convert impinging light to an almost pure and well defined orbital angular momentum state capable of propagating to the far-field.
