  • Synchronizing phases of multiple opitcal channels
    Patent number: 8897656
    Abstract: A system may include one or more devices that may be used to simultaneously measure and modulate phases of a many-channel optical system relative to a high frequency optical carrier. This device may be constructed using analog-to-digital converters, comparators, and distributed timers. A digital processor may be used to recover phase information from the measurements and to calculate an error compared to desired phase. The processor may then apply feedback to a phase modulator to correct the phase.
    Type: Grant

    Date of Patent: November 25, 2014
    Assignee: EM Photonics, Inc.
