Title (EN) CHANNELIZED DISPERSION COMPENSATION MODULE
(FR) MODULE DE COMPENSATION DE DISPERSION CANALISÉE
Abstract: front page image
(EN)There is disclosed an optical device for dispersion compensation of channels within a predetermined wavelength band, comprising: a waveguiding structure; and a grating structure formed in said waveguiding structure; characterized in that said grating structure has a Bragg frequency profile that is divided into contiguous periods, wherein the Bragg frequencies within each period vary between a lower Bragg frequency and an upper Bragg frequency, said lower and upper Bragg frequencies for each period both corresponding to wavelengths outside of said predetermined wavelength band.
(FR)L'invention concerne un dispositif optique de compensation de dispersion de canaux à l'intérieur d'une bande de longueurs d'onde prédéterminée, comprenant: une structure de guidage d'onde; et une structure de réseau formée au sein de ladite structure de guidage d'onde. Ladite structure de réseau présente un profil de fréquences de Bragg divisé en périodes continues. Les fréquences de Bragg dans chaque période varient entre une fréquence de Bragg inférieure et une fréquence de Bragg supérieure, les dites fréquences de Bragg inférieure et supérieure pour chaque période correspondant toutes deux à des longueurs d'onde situées en dehors de ladite bande de longueurs d'onde prédéterminée.
