Abstract
Phase regeneration of phase-shift keying signals is theoretically proposed, we believe for the first time, based on the efficient optical parametric amplification (OPA) process in a highly nonlinear symmetric hybrid plasmonic waveguide. This optimized stacked waveguide with nonlinear organic materials has a relatively low loss of about and an effective nonlinear OPA coupling coefficient up to . The phase-recovery process was achieved in this waveguide within a length as short as 150 μm.
