Abstract

Metasurfaces are known as a powerful tool for complex wavefront shaping. However, two-dimensional metasurface systems of nanoparticles exhibit only a weak spatial asymmetry perpendicular to the surface and therefore have mostly reciprocal optical transmission features. To influence this reciprocity, we present a metasurface design principle for nonreciprocal polarization encryption of holograms. Our approach is based on a two-layer plasmonic metasurface design that introduces a local asymmetry and allows full phase and amplitude control of the transmitted light. We experimentally show that our pixel-by-pixel encoded Fourier-hologram appears in a particular linear cross-polarization channel, while it is disappearing in the reverse propagation direction.
