Abstract: An optoelectronic apparatus includes a semiconductor substrate and multiple arrays of emitters disposed on the semiconductor substrate and configured to emit beams of optical radiation. An optical substrate is mounted over the semiconductor substrate. An optical metasurface disposed on the optical substrate includes multiple optical apertures. Each aperture is configured to receive, collimate and split the beams emitted by a respective array of the emitters into a respective group of collimated sub-beams, so as to direct the collimated sub-beams toward a target at different, respective angles to form a pattern of spots on the target.

Abstract: An optoelectronic apparatus includes a semiconductor substrate and an array of emitters disposed on the semiconductor substrate and configured to emit beams of optical radiation having respective chief rays. An optical diffuser is mounted over the semiconductor substrate and configured to diffuse the beams. Microlenses are disposed between the semiconductor substrate and the optical diffuser in respective alignment with the emitters and configured to steer the beams at different, respective angles, which are selected so that at least some of the chief rays cross one another before passing through the diffuser.
