Abstract

Bi-directional;plasmon vortex;metasurface;linearly-polarized excitation

A nanocavity in a gold thin film is optimized and arranged to form a metasurface. We numerically demonstrate that surface plasmon vortices with directional-tunable orbital angular momenta can be generated under linearly-polarized optical excitation.
