Abstract
Réalisation d'une préforme pour guide d'onde optique à partir d'un élément de départ sensiblement cylindrique sur lequel on applique un matériau particulaire pour y former un revêtement adhérent de verre duquel on extrait l'élément de départ. Un revêtement de carbone est appliqué à la surface périphérique extérieure lisse de l'élément de départ avant application du matériau particulaire. Application à la fabrication de guides d'ondes optiques.
