Abstract

An optoelectronic apparatus includes an array of emitters configured to emit beams of optical radiation. An optical substrate is mounted over the array. An optical metasurface is disposed on the optical substrate and configured to collimate and split each of the emitted beams into a respective group of collimated sub-beams, and to direct the collimated sub-beams toward a target to form a pattern of spots on the target.
