The invention relates to a cost-effective solution for compensating the dispersion of optical signals with different wavelengths. According to the invention, photonic crystals (K1-Kn) are arranged on a common optical waveguide (2). Each photonic crystal (K1-Kn) is set in such a way that it reflects or deflects the signals of one wavelength and allows the signals of other wavelengths to pass through unattenuated. The actual arrangement of the photonic crystals (K1-Kn) on the optical waveguide (2) and the actual arrangement of the deflective elements in the photonic crystal are determined according to the dispersion which is to be compensated between the individual wavelengths. The inventive solution enables high-quality photonic dispersion compensators which are approximately 1000 times shorter than conventional diffraction gratings to be set or adjusted in a fixed manner.

L'invention concerne une solution bon marché pour compenser la dispersion de signaux optiques ayant des longueurs d'onde différentes. Selon l'invention, des cristaux photoniques (K1-Kn) sont disposés sur une fibre optique (2) commune. Chaque cristal photonique (K1-Kn) est réglé de façon à réfléchir ou à dévier les signaux d'une certaine longueur d'onde et à laisser passer les signaux d'une autre longueur d'onde sans les affaiblir. L'agencement effectif des cristaux (K1-Kn) sur la fibre optique (2) et l'agencement effectif des éléments déviateurs dans le cristal sont établis en fonction de la dispersion à compenser entre les différentes longueurs d'onde. La solution de l'invention permet de fabriquer des compensateurs de dispersion photoniques, réglables ou non réglables, de grande qualité, 1000 fois plus courts que les réseaux de diffraction classiques.
