Paper Abstract

Chiral plasmonic structures provide an effective way to couple optical spin with orbital angular momentum, which is suitable to perform manipulation of light beam. This work presents simulation results for a type of spiral-ring plasmonic structures that provide circular polarization selectively in the visible spectrum. The structure consists of discrete spiral gratings that are truncated by rings. With circular polarized lights transmitting the subwavelength structure, surface plasmon polaritons and localized surface plasmons are excited together. Thus, multi-rings spiral plasmonic structures are introduced to obtain high extinction ratio circular dichroism. Moreover, the wavefront phase singularity is also observed in the simulation.
