Original Abstract Submitted

a coherent optical receiver comprises a local oscillator, a polarization-diversity actuator configured for modifying an optical signal output by the local oscillator and a 2�2 coupler for coupling the optical signal output by the polarization-diversity actuator and a modulated optical signal received from a coherent optical transmitter. the local oscillator thus provides a boosting effect to the amplitude-shift keying modulated optical signal. the coherent optical receiver comprises a controlling unit performing a domain-switching procedure acting on ellipticity main axis orientation and/or ellipticity phase shift for coarse control of the polarization-diversity actuator, and a phase-refining procedure acting on a controlled error signal injected in the phase of the optical signal output by the polarization-diversity actuator for fine control of the polarization-diversity actuator.
