Abstract

L'objet de l'invention consiste à prévoir pour les fibres optiques un matériau dont les qualités de transmission soient au moins celles de la silice, mais avec une température de fusion nettement plus basse. Il est prévu d'utiliser un verre fluoré comportant du tétrafluorure de zirconium ou d'hanium, du fluorure de baryum et du fluorure de thorium ou de terre rare. Plusieurs méthodes de fabrication sont décrites. Notamment pour fabriquer une fibre à saut d'indice, on coule d'abord un verre dans un creuset, dont on supprime le fond après un certain temps, pour que la partie encore liquide s'écoule, puis on y coule le coeur. Utilisable pour les fibres à saut ou à gradient d'indice.
