摘要： In an optical transmitter, continuous wave light from a laser passes through a data modulator (DM) for non-return-to-zero (NRZ) encoding of a data stream and through a pulse modulator to add return-to-zero encoding to the modulated optical signal. A modulator controller monitors the output optical signal power, optimizes the bias setting for the DM and the PM, and optimizes the phase relationship between the pulse and data components of the modulated optical signal. For each optimization, a low amplitude and low frequency dither signal is injected at appropriate points in the modulator. A single photo detector and electrical receiver are used in a multiplexed fashion to monitor the optical output signal and derive separate feedback signals. Remaining control circuitry forces a null in a respective residual dither component in the optical output signal to maintain the desired bias level or phase alignment.

摘要： An optical signal regeneration device having an interferometric structure with two arms. Each of the arms has a medium, the optical power output of which is variable with the optical power input. The first arm receives, through an input coupler, a continuous wave and the signal to be regenerated. The second arm receives through the input coupler, a continuous wave signal and a clock signal. A filter, centered on the continuous wave wavelength, receives the output signal of the interferometric structure through the coupler. The filter output signal constitutes the regenerated 3R signal.
