  • Publication number: 20020005970
    Abstract: The method for dispersion compensation and the dispersion compensator that carries out the method, split an optical signal into two frequency bands fH and fL. The frequency bands are transmitted in two Mach-Zehnder arms, where they are subjected to different propagation delays. When the frequency bands are recombined, they are polarized orthogonally with respect to one another.

  • Patent number: 6233375
    Abstract: The component comprises structures, achieved in integrated optics, exerting predetermined stresses on a light wave guiding waveguide so as to maintain or modify in predetermined manner the polarization state of an incident light wave. These structures are formed by at least one segmented plane waveguide arranged laterally with respect to the light wave guiding waveguide and formed by parallel lateral waveguides perpendicular to the longitudinal axis of the light wave guiding waveguide. These structures are achieved at the same time as the light wave guiding waveguide, the segmented plane waveguides having refractive indexes lower than or equal to those of the light wave guiding waveguide. Such structures can be arranged symmetrically or asymmetrically, alternately on each side of the light wave guiding waveguide.
