Design Rules for Structural Colors in All-Dielectric Metasurfaces: From Individual Resonators to Collective Resonances and Color Multiplexing

Résumé

In this work, we comprehensively review Mie resonator-based and nonlocal resonant metasurfaces working in the reflection configuration for color printing applications, with particular attention to high observation angle applications. While Mie resonator-based metasurfaces are found to be simple to design and present low sensitivity to the observation angle, they present the drawback of low color saturation. By contrast, square lattice photonic crystal waveguide-based metasurfaces show very selective spectral responses, yielding pure colors but with high selectivity on the observation angle. In order to harness the exceptional color-filtering properties of photonic crystal waveguides and maintain the desired spectral response under oblique angles of observation, a rectangular lattice for the crystal structure is proposed. We provide design rules and examples in order to produce angularly robust, vivid colors at any desired wavelength within the visible spectrum. Furthermore, by exploiting the polarization of the incident light and adapting the design of the photonic crystal structures, we demonstrate color multiplexing for cryptography applications.
