CA 2243858

The invention relates to integrated interferometric structures, namely for optical signal wavelength converters. A first and second branch of the structure, comprising at least a first semiconductor optical amplifier (OA1), are coupled to input (OA4, OA5) and/or output (OA3) peripheral semiconductor optical amplifiers. The structure is distinctive in that it comprises an attenuation section (10) between the output of at least one amplifier (OA1) of one of the branches and the input of the output peripheral amplifier (OA3) and/or in that the length of the waveguide of at least one peripheral amplifier (OA3, OA4, OA5) is less than 300 µm. For use in telecommunications, particularly signal routing. .

L'invention se rapporte à des structures interférométriques intégrées, notamment pour convertisseurs de longueur d'onde de signaux optiques. Une première et une seconde branche de la structures, comportant au moins un premier amplificateur optique semi-conducteur (OA1), sont couplées à des amplificateurs optiques semi-conducteurs périphériques d'entrée (OA4, OA5) et/ou de sortie (OA3). La structure est caractérisée en ce qu'elle comporte une section d'atténuation (10) entre la sortie d'au moins un amplificateur (OA1) d'une des branches et l'entrée de l'amplificateur périphérique de sortie (OA3) et/ou en ce que la longueur du guide d'onde d'au moins un amplificateur périphérique (OA3, OA4, OA5) est inférieure à 300µm. Utilisation dans le domaine des télécommunications, en particulier pour le routage de signaux.
