The photonic integrated circuit, the spacer substrate, the plurality of optical cells, the beam combiner, and the photodetector are integrated as a single monolithically formed optical head. Each optical cell includes a focusing optical element formed on the spacer substrate and configured to focus the light through the substrate and onto a folding element. The folding element is integrated into the photonic integrated circuit to couple light incident on the optical cell into a waveguide. The waveguide is coupled to the phase shifter to transport the light reflected by the folding element through a phase shifter. The phase shifter is coupled to the focusing optical element to shift a phase of an optical signal received by the focusing optical element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Planar optical head for free space optical communications, coherent LIDAR, and other applications","description":"A multi-aperture optical system includes a photonic integrated circuit, a spacer substrate coupled to the photonic integrated circuit, a plurality of optical cells, a beam combiner, and a photodetecto","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10545289","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
