Patent number: 11159234Abstract: A scalable interferometric imaging and laser communications system integrated as a single satellite payload is provided. Multiple lenslets are coupled via associated waveguides to a single multi-mode interferometer in an N-arm beam combination using a PIC based architecture. The multi-mode interferometer is coupled to a communication sensor via a splitter and to an imaging sensor via an array waveguide grating, which in turn are coupled to a processor. The system interferes all input waveguides simultaneously and provides OPD control over individual input waveguides.Type: GrantFiled: January 21, 2020Date of Patent: October 26, 2021Assignee: LOCKHEED MARTIN CORPORATIONInventors: Guy Chriqui, Nicolas James Deshler, Anthony Cecere Klee

Patent number: 10663282Abstract: A fiber-coupled phased-array includes a first photonic integrated circuit (PIC) and a second PIC. The first PIC includes a first set of lenslets and waveguides. The second PIC includes a second set of lenslets and waveguides and is placed at a distance from the first PIC. The optical fibers couple the first PIC to the second PIC and form an interferometric imager that can sample spatial frequencies of a target. Optical delay errors induced by a relative placement of the first PIC and the second PIC are compensated for.Type: GrantFiled: December 10, 2018Date of Patent: May 26, 2020Assignee: LOCKHEED MARTIN CORPORATIONInventors: Chad Elliott Ogden, Guy Chriqui, Gregory Samuel Feller

Patent number: 10564373Abstract: A modular assembly for an imaging system can allow precision alignment to occur in isolated manufacturing stages, with the separate components being assembled together in later stages. An exemplary system includes a support structure, multiple imaging modules exchangeably coupled to the support structure and each including lenslets and a photonic integrated circuit (PIC) device arranged to receive light from the lenslets, multiple fiber arrays each connected to corresponding one of the multiple imaging modules, and a camera system connected to the fiber arrays. The lenslets the PIC device can be integrally coupled prior to assembly with the support structure, so that precise alignment of the lenslets with respect to the PIC device is performed in isolation.Type: GrantFiled: January 19, 2018Date of Patent: February 18, 2020Assignee: Lockheed Martin CorporationInventors: Chad E. Ogden, Guy Chriqui

Publication number: 20200049886Abstract: 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 photodetector coupled to the beam combiner. 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.Type: ApplicationFiled: January 8, 2019Publication date: February 13, 2020Inventors: Guy CHRIQUI, Chad Elliott OGDEN, Paul J.
