摘要：A dispersion compensator for the compensation of chromatic dispersion in a
multi-channel light signal is provided. The compensator includes a pair of opticalstructures each having a waveguide and a Bragg grating provided therein. The Bragggrating has a plurality of grating components, each associated with one or a few of thechannels to be compensated. An optical assembly propagates the light signal
sequentially through both optical structures. The periods of the grating components areselected to allow compensation of chromatic dispersion experienced by this particularchannel or these particular channels, thereby taking into account the dispersion slope ofthe light signal. Tuning means are also provided in order to adjust the dispersion of thegrating components of each optical structures, and proper selection of the tuningparameters allows tuning independently both the dispersion and dispersion slope.
