Abstract

ON FABRIQUE DES FIBRES OPTIQUES DE SECTION QUELCONQUE EN ETIRANT UNE TIGE VITREUSE DONT LA TEMPERATURE EST REGLEE AU POINT DE RAMOLLISSEMENT. PLUSIEURS COUCHES DE MATERIAU PULVERULENT VITRIFIABLE OU VITREUX PROVENANT D'UN DISTRIBUTEUR 7 SONT DEPOSEES AU SOMMET DE LA TIGE INITIALE 8, LES COUCHES ETANT SOUMISES L'UNE APRES L'AUTRE AU COURS DE LEUR FABRICATION, A UN DOPAGE APPROPRIE PAR IMPLANTATION D'IONS GENERATEUR D'IONS 9 AFIN D'OBTENIR UNE REPARTITION AXIALE ET RADIALE DONNEE DE L'INDICE DE REFRACTION DANS LA FIBRE FINALE; EN MEME TEMPS, LA TIGE AVANCE PROGRESSIVEMENT DANS LE SENS AXIAL, REALISANT AINSI UNE PREFORME INTERMEDIAIRE 8 QUI EST AMENEE DANS UNE ZONE 4 DANS LAQUELLE SA TEMPERATURE EST REGLEE A UN NIVEAU AUQUEL LA PREFORME PEUT ETRE ETIREE DANS UN DISPOSITIF 5 POUR ETRE TRANSFORMEE EN FIBRE.
