Abstract: An optical structure and devices based thereon for the compensation of chromatic dispersion in a multi-channel light signal are provided. The optical structure includes a waveguide and a Bragg grating provided therein. The Bragg grating has a plurality of grating components, each associated with one or a few of the channels to be compensated. The period of each grating component is selected to allow compensation of chromatic dispersion experienced by this particular channel or these particluar channels, thereby taking into account the wavelength-dependent dispersion slope of the light signal.

Abstract: A fine-tuning assembly for an optical grating in an optical fiber is provided. The fiber is mounted under tension in a hollow structure which has a sliding member longitudinally slideable therein. The fiber is attached to both the sliding member and hollow structure. A slanted passage is provided in the sliding member, forming a small angle with the transversal, and a wedge member is slideably inserted in this passage. To fine-tune the spectral response of the grating, the wedge member is transversally displaced without any longitudinal displacement, preferably by the action of screws, thereby pushing on its walls to longitudinally slide the sliding member and adjust the tension in the fiber.

Abstract: Methods to improve the optical properties of Bragg gratings are disclosed. A first method includes a post correction of the refractive index profile by applying an average index correction thereto. The average index correction is obtained through an analysis of the defects of the refractive index profile characterised through a reconstruction thereof. A second method includes a pre-correction to the refractive index profile by characterising the defects of a test grating, and again calculating an average index correction based thereon. Further gratings are then made using a corrected refractive index profile.

Abstract: A method for manufacturing complex gratings masks having phase shifted regions and a holographic set-up for making the same are disclosed. The method, which can be easily automated, allows to produce arbitrary phase shift in holographically recorded gratings with high precision. In a preferred embodiment, the phase is controlled by a fringe locking system with a movable locking detector and a phase measuring device such as a camera for example, thereby allowing to provide a real-time phase locking and a real-time calibration of the set-up.
