Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View

open access: yesAdvanced Photonics Research, EarlyView.
Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.
