ABSTRACT:
Disclosed herein is an all-optical regenerator including two stripe waveguides, each waveguide having an input and an output optical contacts; a nonlinear ring resonator comprising a source laser, a multi-sectional semiconductor laser, mirrors, four phase modulators, and means for controlling the source laser, the multi-sectional laser and the four phase modulators; and two directional couplers, each coupler being positioned between the nonlinear ring resonator and each of the waveguides. The all-optical regenerator in accordance with the present invention performs such functions as clock recovery, pulse reshaping and amplification of optical signals without going through intermediate electronic stages.
