Title (EN) THERMAL RIPPLE-COMPENSATING, GAIN-FLATTENING FILTER FOR AN OPTICAL AMPLIFIER
(FR) FILTRE COMPENSATEUR D'ONDULATION THERMIQUE, EGALISATEUR DE GAIN POUR AMPLIFICATEUR OPTIQUE
Abstract:
(EN) An optical device including an optical amplifier (12) to amplify optical signals received through an optical input, and to supply the amplified optical signals from an optical output, and an optical filter component (20) to compensate for variations in the gain spectrum of the optical amplifier (12) that occur as a function of wavelength and operating temperature. The optical filter component includes a first optical filter (22) having an athermalized transmission spectrum and a second optical filter (24) having a transmission (or insertion loss) spectrum that varies as a function of operating temperature.
(FR) La présente invention concerne un dispositif optique comprenant un amplificateur optique permettant d'amplifier des signaux optiques reçus à travers une entrée optique, et à fournir les signaux optiques amplifiés à partir d'une sortie optique, et un composant de filtre optique permettant de compenser des variations au niveau du spectre de gain de l'amplificateur optique qui se produisent en fonction de la longueur d'onde et de la température de fonctionnement. Le composant de filtre optique comprend un premier filtre optique possédant un spectre de transmission insensible aux variations thermiques et un second filtre optique possédant un spectre de transmission (ou perte d'insertion) qui varie en fonction de la température de fonctionnement.
