ABSTRACT:
A device for tailoring the chromatic dispersion of a multi-channel light signal is proposed. The device includes at least two waveguides coupled in a cascade, each provided with a spatially distributed optical filter. The group delay response of the filters is designed so that the group delay of each channel of the light signal can be tuned independently of the others, and an appropriate tuning mechanism is provided for this purpose. The device may advantageously be used as a flexible dispersion compensator.
