Abstract
L'invention porte sur une fibre de guide d'onde optique à mode unique possédant une âme segmentée dans laquelle le segment central est un vide (16). La forme et l'extension radiale des segments de l'âme sont sélectionnées de façon à avoir une pente de faible dispersion ainsi qu'une surface efficace importante et une bonne résistance à la courbure. L'invention porte également sur des réalisations de profiles à indice de réfraction possédant deux ou trois segments annulaires (2, 6, 8) entourant le vide central. La présence du vide offre les avantages d'un indice relatif négatif centré dans la région de l'âme sans les difficultés de traitement associées à l'utilisation de dopants qui réduisent l'indice de réfraction de la fibre du guide d'onde.
