Abstract

La présente invention concerne des dispositifs interférométriques et en treillis, stables vis à vis de l'environnement, qui présentent une faible perte d'excédent et une faible perte dépendant de la polarisation. Ces dispositifs sont de fabrication simple et économique. Le bruit modal au niveau des épissures entre les fibres amorces du dispositif et la fibre du système est minimisé ou supprimé. La présente invention concerne un dispositif optique permettant de filtrer un signal lumineux. Ce dispositif optique offre une réponse spectrale accordable. Il comporte une fibre optique présentant une région de coeur et une gaine présentant un indice de réfraction n2. La première région de coeur comprend un coeur présentant un indice de réfraction n1, ainsi qu'un premier régulateur de couplage de fibres, intégré à la première fibre optique. Ledit premier régulateur de couplage de fibres couple le signal lumineux entre un premier chemin optique et un deuxième chemin optique et empêche sensiblement le couplage du signal lumineux dans un troisième chemin optique. La présente invention comprend un procédé pour accorder le filtre optique coaxial monolithique pour qu'il présente des caractéristiques spectrales prédéfinies. De l'énergie thermique est appliquée sur au moins une partie d'accord de spectre dudit filtre optique coaxial monolithique. L'énergie thermique produit une modification spectrale prédéfinie dans la réponse spectrale du filtre optique coaxial monolithique.
