Abstract

We develop frequency-preserving parametric tunable dispersion compensator (P-TDC) with polarization diversity for simultaneous dispersion compensation of wavelength division multiplexing channels. The in-line polarization-insensitive P-TDC is composed of cascaded parametric tunable frequency converters based on degenerate four-wave mixing process in polarization-maintaining highly nonlinear fibers with a low dispersion slope. Dispersion-managed error-free transmission of four channels of 43 Gb/s nonreturn-to-zero ON–OFF keying signal is successfully demonstrated over 126 km dispersion-shifted fiber with the in-line polarization-insensitive P-TDC.
