Abstract

Guide d'ondes optiques à gradient d'indice de grande ouverture numérique. On forme un élément tubulaire en verre à deux constituants. On modifie radialement la concentration du premier constituant pour obtenir un indice variant radialement et on modifie radialement la concentration de l'autre constituant pour compenser la variation radiale de coefficient de dilatation thermique provoquée par la variation du premier constituant. Application aux guides d'ondes à grande ouverture numérique.
