    All-dielectric structural coloration empowered by bound states in the continuum by Zheng Hong, Hu Haiyang, Weber Thomas, Wang Juan, Nan Lin, Zou Bingsuo, Maier Stefan A., Tittl Andreas

    Published 2024-10-01
    “…Here, we demonstrate an all-dielectric metasurface empowered by photonic bound states in the continuum (BICs), which supports sharp resonances throughout the visible spectral range, ideally suited for producing a wide range of structural colors. The metasurface design consists of TiO2 ellipses with carefully controlled sizes and geometrical asymmetry, allowing versatile and on-demand variation of the brightness and hue of the output colors, respectively.…”
