IN-FIELD DROOP MEASUREMENT AND COMPENSATION FOR COHERENT OPTICAL TRANSCEIVER
Abstract: a self-calibrating transceiver includes a set of digital to analog converters configured to process a comb calibration waveform, at least one iq modulator configured to generate at least one optical signal comprising i and q components operably coupled from the set of digital to analog converters. a receiver photonics circuit is configured to convert the coupled optical signals to electrical signals. the receiver photonics circuit includes a set of analog to digital converters coupled to convert the electrical signals to digital signals representative of the comb calibration waveform in cartesian iq format. processing circuitry is coupled to determine at least magnitude and/or phase of the digital signals and generate filter coefficients based on a comparison of at least magnitude and/or phase to the comb calibration waveform.
