Polarization-controlled generation of Airy plasmons.

Plasmonic metasurfaces have shown great potential to generate Airy plasmons on a metal surface, but the building block of metasurfaces in these works is purposely designed to operate under limited polarization states for the incident light. Here, it is shown that paired nanoslit resonators on a metal surface can provide Airy phase distributions under different polarization incidences. We demonstrate that Airy plasmons can be generated under x-, …
