  • 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.

  • Phased-array coherent transceiver
    Patent number: 10419120
    Abstract: A phased-array coherent transceiver system includes a transceiver array including multiple receive (RX) optical elements, a number of RX optical fibers, and an optical receiver. The RX optical elements are coupled to the optical receiver via the RX optical fibers. The optical receiver includes multiple phase modulators, each phase modulator processes a phase of an optical signal received from an RX optical element.

  • Spatially dephasing local oscillator for coherent free-space optical communications
    Patent number: 10122471
    Abstract: A coherent transceiver system includes a local oscillator (LO) light source to generate an LO optical signal. An adaptive fiber array is coupled to the LO light source to dephase the LO optical signal. A balanced detector is coupled to the adaptive fiber array to receive a dephased LO signal from the adaptive fiber array and an optical input signal and to generate a heterodyne signal. A controller receives the heterodyne signal and generates one or more control signals. The adaptive fiber array utilizes the control signals to dephase the LO optical signal.
