Abstract

We design, fabricate and experimentally demonstrate bifunctional gap-plasmon metasurfaces for visible light, allowing simultaneous polarization-controlled unidirectional surface plasmon polariton (SPP) excitation and beam steering at normal incidence. The fabricated metasurfaces can efficiently launch unidirectional SPP within the wavelength range of 600-650 nm with an averaged coupling efficiency of >25% and extinction ratio exceeding 20 dB under normal illumination with the x-polarized beam. Meanwhile, broadband beam steering has been experimentally realized for y-polarization in the spectrum ranging from 580 nm to 700 nm.
