Disclosed is a single mode optical waveguide fiber having a segmented core in which the central segment is a void (16). The shape and radial extent of the core segments are selected to provide a low dispersion slope together with large effective area and good bend resistance. Embodiments of the refractive index profiles in accord with the invention are shown having two or three annular segments (2, 6, 8) surrounding the central void. The presence of the void provides the benefits of a negative relative index located centrally in the core region without the process difficulties associated with the use of dopants that decrease the refractive index of the waveguide fiber.

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.
