Abstract: A device includes an array of light sources configured to emit light beams, and a metasurface including a plurality of nanostructures and configured to receive and deflect the light beams emitted by the array of light sources. The metasurface includes a plurality of regions. Nanostructures in different regions of the plurality of regions are configured to deflect center light rays (with peak intensity) of the light beams into different directions towards a target, such as display optics of a near-eye display. In some embodiments, nanostructures in each region of the plurality of regions are configured to deflect center light rays of light beams of two or more different colors into a same direction or similar directions towards the target.
