Abstract
Cette invention a trait à un ensemble masque de phase accordable (10), utilisé pour photo-induire un filtre à longueur d'onde optique dans un guide d'onde optique. Cet ensemble masque de phase comporte un masque de phase dont une longueur s'étend entre deux extrémités longitudinales opposées. Ce masque de phase comporte des indentations de réseau de diffraction, faisant saillie depuis sa face, et périodiquement réparties dan le sens de la longueur. On peut accorder la périodicité de ce masque de phase en modifiant de manière réversible la longueur s'étendant entre les deux extrémités longitudinales, notamment en raccourcissant ou en étirant le masque. De la sorte, une configuration d'interférence d'un faisceau lumineux traversant le masque de phase est également accordée, de qui permet d'agir sur les caractéristiques d'un filtre à longueur d'onde photo-induit au moyen de cet ensemble masque.
