Abstract
Optical components such as components that emit light and components that detect light may be provided. Optical components that emit light may include displays having arrays of display pixels with respective light-emitting devices such as crystalline semiconductor light-emitting diodes. Optical components that detect light may include image sensors or other components with arrays of photodetectors. The light-emitting devices and photodetectors in the optical components may be overlapped by metalenses such as multielement metalenses. A multielement metalens may have a first metalens element formed from a first layer of nanostructures arranged and an overlapping second metalens element formed from a second layer of nanostructures. Light sources may be provided on a semiconductor and metalens nanostructures may be formed on an opposing surface of the semiconductor.
