  • Fiber-coupled phased array of photonic integrated circuit imagers
    Patent number: 10663282
    Abstract: 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.

  • Multi-mode wavelength division multiplexing for free-space optical communications
    Patent number: 10547405
    Abstract: A multi-mode wavelength-division multiplexing (WDM) receiver includes a receiver head to receive a free-space optical (FSO) signal. A multi-mode demultiplexers (demux) is coupled to the receiver head via a multi-mode fiber to generate a number of optical signals based on the FSO signal. A number of repeaters modify the optical signals and generate a number of single-mode optical signals.
