Abstract

Ce circuit en guide d'ondes optique comprend une pluralité de guides d'ondes de différentes longueurs. On a formé des rainures (12) dans le guide d'ondes en enlevant la gaine supérieure et le coeur du guide d'ondes (4) ou en enlevant la gaine supérieure, le coeur et la gaine inférieure du guide d'ondes (4) et on a rempli ces rainures d'une matière (10) possédant une courbe coefficient de température/indice de réfraction différente de la courbe coefficient de température/indice de réfraction efficace du guide d'ondes. La différence entre les longueurs des parties enlevées des guides d'ondes adjacents est proportionnelle à la différence entre les longueurs des parties restantes des guides d'ondes adjacents.
