Abstract

We design, fabricate and experimentally demonstrate a focused vector-beam (FVB) operating in reflection by designing gap-surface plasmon metasurfaces that enables efficient linear-polarization conversion and total phase control over the reflected light. The proof-of-concept fabricated sample efficiently generates FVBs in the wavelength range of 800-950 nm with the averaged absolute efficiencies reaching as high as 35% and 34% for the radially-polarized and azimuthally-polarized beams, respectively.
