Publication number: 20230367172Abstract: Light is provided to optical antennas (OAs) separated by a first set of spacings in a first OPA. Phases of light provided to respective OAs are controlled to form a transmitted beam whose angle is steered so that first and second lobes of a first angular intensity distribution (AID) scan over first and second portions of a region, respectively. Light is received from OAs separated by a second set of spacings in a second OPA into which light is received from directions associated with a second AID. The first lobe of the first AID and a first lobe of the second AID substantially overlap in angle during the scan of the first lobes, and the second lobe of the first AID and a second lobe of the second AID substantially overlap in angle during the scan of the second lobes.Type: ApplicationFiled: May 5, 2023Publication date: November 16, 2023Applicant: Analog Photonics LLCInventors: Jordan Goldstein, Christopher Vincent Poulton, Michael Robert Watts, Peter Nicholas Russo, Oleg Shatrovoy
