Mitigating Chromatic Dispersion with Hybrid Optical Metasurfaces

Advanced Materials, 2018
AbstractMetasurfaces control various properties of light via scattering across a large number of subwavelength‐spaced nanostructures. Although metasurfaces appear to be ideal photonic platforms for realizing and designing miniaturized devices, their chromatic aberrations have hindered the large‐scale deployment of this technology in numerous ...
