    摘要： A method for receiving an optical signal is included where an ingress signal is split into a first portion and a second portion. A relative delay is induced between the first portion and the second portion, which are optically interfered to generate at least one interfered signal. Quality criteria of a monitored signal at least based on the at least one interfered signal is monitored so that a relative delay based in the quality criteria may be adjusted.

    摘要： The present invention provides an improved optical frequency demodulation technique for extracting overhead information from an optical channel signal carrying both high bit rate payload and low rate overhead data. The invention makes use of asymmetrical Mach-Zehnder interferometry (AMZI) in an optical frequency demodulator to efficiently extract the overhead information from the optical channel signal by frequency discrimination without necessitating a complete demodulation of the optical channel signal. By comparison to existing demodulation schemes, the invention provides an all-optical low cost, high gain technique for recovering the overhead data which improves the payload signal-to-noise ratio and enhance performance.

    摘要： In accordance with various aspects of the disclosure, a method, an apparatus and a system for characterizing and compensating for deterministic phase nonlinearities and distortion inherent in radio frequency and optical components utilized to synthesize a single sideband suppressed carrier optical waveform in the presence of random phase noise generated by an optical carrier source is disclosed. The method comprises mixing a modulated optical signal with a continuous wave optical signal in an optical coupler; optically heterodyning the mixed signal output from the optical coupler in a detector to produce a radio frequency waveform; and analyzing the produced radio frequency waveform in a processor based on a phase history of a preselected continuous wave signal to measure distortion characteristics of the radio frequency modulated optical signal.
