Silicon nitride metalenses for unpolarized high-NA visible imaging
/ Authors
/ Abstract
We experimentally demonstrate the high-NA silicon nitride metalenses with centimeter aperture and micro size in visible region, fabricated by 695-nm-thick hexagonal silicon nitride arrays. The potential application of wide viewing-angle functionality has also been shown.
