Abstract :
We realized metasurface spiral plasmonic lenses, mitigating efficiency and functionality issues of conventional plasmonic lenses. The lens enhances the efficiency of linear-polarization-invariant focusing and enhances even further the efficiency of high contrast, circular dichroic detection.
