    Abstract: A system for compensating chromatic dispersion includes a long variable pitch Bragg grating written in an optical fiber in which wavelength division multiplexed transmission channels propagate. A system for generating a thermal gradient includes at least two heating systems distributed over the grating and controlled independently of each other to compensate simultaneously the chromatic dispersion on a plurality of transmission channels.

    Abstract: The present invention relates to a Bragg grating filter optical waveguide device, comprising an optical fiber provided with a Bragg grating region which is externally strained to alter the range of chirping. The external strain is induced by a gradient-generating mechanical body bonded onto the length of the fiber grating.
