A new method for chromatic-dispersion compensation is proposed and demonstrated. This method can produce a chromatic dispersion practically in a wide range from -2000 ps/nm to +2000 ps/nm and can compensate simultaneously for the dispersion of over 60 wavelength channels with 100 GHz spacing in a WDM system which has a total bandwidth of over 50 nm. This method has further good features such as very small polarization-state dependence, mechanically variable chromatic dispersion, and the potential for small packaging. It was experimentally confirmed that this method compensated for the chromatic dispersion accumulated through an up to 110 km standard single mode fiber at 1.55 pm wavelength and that 10 Gb/s signal quality was clearly recovered after the 110 km transmission.
