(FR) GUIDE D'ONDE DOPE AU TANTALE ET SON PROCEDE DE FABRICATION
Abstract
(EN)
The present invention is directed to low loss optical waveguides doped with tantala and methods of manufacturing such waveguides. SiO2 soot is doped with Ta2O5 to form a soot blank which is consolidated under conditions suitable to prevent the crystallization within the Ta2O5-SiO2 containing waveguides. The resulting rod is then either drawn into an optical fiber or overclad and subequently drawn into an optical fiber. High temperature consolidation in either a gaseous atmosphere or vacuum atmosphere is used to sinter and vitrify the soot blank prior to drawing to produce a low loss optical waveguide fiber.
(FR)
La présente invention porte sur des guides d'onde optiques à faible perte dopés au tantale et sur leurs procédés de fabrication. Une suie de SiO2 est dopée au Ta2O5 de façon à obtenir une ébauche qui est consolidée dans des conditions appropriées pour prévenir la cristallisation dans les guides d'onde contenant Ta2O5-SiO2. La tige obtenue est alors étirée sous forme d'une fibre optique ou recouverte d'une gaine et ensuite étirée sous forme d'une fibre optique. La consolidation à haute température sous atmosphère gazeuse ou à vide est utilisée pour fritter et vitrifier l'ébauche avant l'étirage afin de produire une fibre optique de guide d'onde à faible perte.
