Abstract

a. L'invention concerne une fibre optique comportant une âme ou un noyau 10 en silice pourvu d'un revêtement il et dont l'indice de réfraction varie radialement grâce à la distribution dans le noyau de deux substances dopantes susceptibles de modifier l'indice de réfraction. b. Les deux substances dopantes sont de nature à augmenter l'indice de réfraction du noyau et sont constituées par l'anhydride phosphorique et le bioxyde de germanium. c. Application aux systèmes de communication par voie optique.
