Abstract
La modification de l'indice de réfraction suivant le rayon, qui est importante pour les fibres optiques autofocalisantes, est obtenue par exécution d'un procédé de dépôt chimique en phase vapeur activé par plasma avec abaissement continu de la teneur en oxygène du mélange gazeux et/ou de la température de la paroi du tube pendant la formation du revetement. Application à la fabrication des fibres optiques.
