The invention includes environmentally stable athermalized optical fiber gratings and methods of making such a stabilized optical waveguide fiber grating. Stable humidity-resistant athermalized fiber Bragg gratings (19) are provided by stabilizing a negative thermal expansion substrate (20) and utilizing a durable frit (24) to attach the fiber Bragg grating to the substrate.
La présente invention concerne des réseaux à fibre optique insensibles aux variations de température, stables à l'environnement, ainsi que des procédés de fabrication d'un tel réseau à guide d'onde optique stabilisé. Des réseaux de Bragg à fibre (19) stables à la température et résistants à l'humidité sont obtenus par stabilisation d'un substrat à expansion thermique négative (20) et utilisation d'un verre de scellement (24) afin de fixer au substrat le réseau de Bragg à fibre.
