Achromatic metalenses for full visible spectrum with extended group delay control via dispersion-matched layers
Abstract Achieving achromaticity across the visible light spectrum is crucial for metalenses in imaging systems. Single-layer metalenses struggle with weak focusing power or small aperture sizes due to inadequate group delay control. Multilayer metalenses offer some improvement but come with increas...
