Title (EN) DISPERSION MANAGED OPTICAL WAVEGUIDE FIBER
(FR) FIBRE DE GUIDE D'ONDE OPTIQUE A COMPENSATION DE DISPERSION
Abstract: front page image
(EN)Disclosed is a single mode optical waveguide fiber designated for compensating for positive dispersion in optical telecommunications systems. A key characteristic of the invention is that the novel dispersion compensating waveguide, viz., a waveguide having large negative dispersion, contains no dopants, such as fluorine, which lower the refractive index of silica. A refractive index profile design which includes a high refractive index center segment (5) surrounded by a plurality of alternating high (6, 10, 13) and low refractive index segments, provides a dispersion compensation fiber which has the optical properties required for the system to be compensated without sacrificing bend resistance, increasing splicing loss, or elevating polarization mode dispersion.
(FR)L'invention porte sur une fibre unique de guide d'onde optique conçue pour compenser la dispersion positive de systèmes optiques de télécommunications. La caractéristique clé de l'invention est que ce nouveau guide d'onde à compensation de dispersion tel qu'un guide d'onde à grande dispersion négative contient des dopants telle que la fluorine qui réduisent l'indice de réfraction de la silice. Une conception à profile d'indice de réfraction comprenant un segment central (5) à indice de réfraction élevé, entouré d'une pluralité de segments à indices de réfraction alternés, élevés (6, 10, 13) et faibles, permet de produire une fibre à compensation de dispersion possédant les propriétés requises pour le système à compenser sans annuler la résistance à la courbure, sans accroître les pertes aux points de raccordement ou sans élever la dispersion en mode de polarisation.
