Title (EN) SOLID STATE ETALONS WITH LOW THERMALLY-INDUCED OPTICAL PATH
(FR) ETALONS A L'ETAT SOLIDE A FAIBLE VARIATION THERMO-INDUITE DU CHEMINEMENT OPTIQUE
Abstract: front page image
(EN)An etalon (100) is disclosed comprising a first ruble or strontium titanate material (115) having a first coefficient of thermal optical path length change fl, that has a negative value, coupled with a second material (120) having a coefficient of thermal optical path length change ß2 that is positive, and an optical path extending through the first material and the second material, such that the effective temperature coefficient of the optical path length is close to zero. Further, the total optical path length in the cavity gives a desired free spectral range of the etalon. Etalons composed of a single crystalline material are also disclosed. Such materials may include crystalline quartz.
(FR)L'invention porte sur un étalon (100) comprenant un premier matériau (115), de rutile ou de titanate de strontium, présentant un premier coefficient $g(b) négatif de variation thermo-induite de la longueur du cheminement optique, couplé à un deuxième matériau (120) présentant un deuxième coefficient $g(b)2 négatif de variation thermo-induite de la longueur du cheminement optique (120), et un cheminement optique traversant le premier matériau et le deuxième matériau de manière à ce que le coefficient de température résultant de la longueur du cheminement optique soit proche de zéro. En outre, la longueur totale du cheminement optique dans la cavité fournit l'étendue spectrale libre désirée de l'étalon. On a ainsi des étalons composés d'un unique matériau cristallin pouvant inclure du quartz cristallin.
