Abstract: A metalens and a metalens array having a bounded angular field of view are disclosed. The metalens includes a substrate and a two-dimensional (2D) grid over the substrate to divide the substrate into a 2D array of meta-units. Each meta-unit in the 2D array includes a nanostructure and a portion of the substrate that supports the nanostructure. Moreover, each meta-unit is configured with an angular-dependent transmission or reflection coefficient that decreases with an increasing incident angle of an illumination. Moreover, the metalens passes an incident light having an incident angle less than a cutoff angle and rejects an incident light having an incident angle greater than the cutoff angle. The metalens can be used a base unit for constructing a metalens array by tiling copies of the metalens into a 2D array of the metalens to achieve a significantly larger field-of-view.
