Abstract
The present invention provides an improved chromatic dispersion compensator. The compensator includes an input optical fiber; an output optical fiber; a collimator optically coupled to the input and output optical fibers; and an interferometer optically coupled to the collimator at a side opposite to the input and output optical fibers. In a preferred embodiment, the interferometer is a Gires-Tournois interferometer. A plurality of sequentially optically coupled chromatic dispersion compensators may also be used. 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.
