Abstract
A method for compensating for chromatic dispersion of an optical signal includes: receiving the optical signal from an input fiber; collimating the optical signal using a collimator; delivering the collimated optical signal to a Gires-Tournois interferometer; reflecting a chromatic-dispersion-compensated optical signal from the Gires-Tournois interferometer to the collimator; focusing the chromatic-dispersion compensated optical signal into an output fiber. The compensator in accordance with the present invention provides flexibility in producing periodically varying chromatic dispersion so as to compensate for unwanted periodic chromatic dispersion produced in an interferometric interleaved channel separator. Also, the compensator enables compensation of fiber optic chromatic dispersion.
