Circular Polarization Analyzer Based on the Combined Coaxial Archimedes’ Spiral Structure

We have designed a novel plasmonic lens for the circular polarization analyzer based on the combined coaxial Archimedes’ spiral structure which is composed of a Archimedes’ spiral slit (ASS) surrounded by coaxial Archimedes’ spiral gratings (ASG) on the both sides of the metal film. The designed structure is sensitive to polarization of the incident circularly polarized light, and it can realize the focusing effect under circular polarization illumination with specific handedness and defocusing effect under the other handed circular polarization illumination. This phenomenon of spin-dependent intensity distribution can be attributed to the presence of geometric phase effect of ASS. The simulated results show that the combination of the ASS and ASG has a higher efficiency and better performance than the traditional pure ASS.
