Wide-Band and -Range Tunable Dispersion Compensation Through Parametric Wavelength Conversion and Dispersive Optical Fibers

An intrinsically ultrafast, wide-band, and -range tunable dispersion compensation (TDC) is realized through parametric wavelength conversion in conjunction with fibers with large dispersion slope such as dispersion compensating fibers. The proposed schemes have unique potentials that they can operate with fast response in a truly colorless manner and are capable of producing two orders of magnitude larger bandwidth-dispersion product than conventional ones. After the discussions on the operating principle and design issues, a proof-of-concept experiment is performed to verify the static operations achieving a tunable dispersion range larger than plusmn280.5 ps² for 2.47 ps optical pulses.
