Spectral Condensing of All‐Dielectric Structural Colors via Cascaded Formation of Self‐Similar Beams

ABSTRACT Achieving strongly saturated structural coloring in pixels made entirely of low‐index dielectrics, such as polymers or glass, is a challenging task as they lack the index contrast for narrowband resonances. Forming gratings or photonic crystals is an alternative, but the...
