Thin-film polymeric metasurfaces for visible wavelengths

Abstract

Photonic metasurfaces are typically realized by the periodic distribution of meta-atoms, which incorporate two or more different materials. This requirement introduces constraints in the design and fabrication that are particularly significant for flexible and conformable metasurfaces. Here, we report on the design and fabrication of efficient, polarization-independent, all-polymeric metasurface membranes for holographic applications in the visible range. These results will facilitate the large-scale production of holographic metasurfaces, advancing their adoption in practical, real-life scenarios.
