Abstract

L'invention concerne une fibre guide d'onde optique monomode présentant une âme segmentée. Les indices relatifs, les courbes de l'indice de réfraction, et les rayons des segments de cette âme sont choisis de manière à obtenir des propriétés pouvant être utilisées avec avantage dans des environnements hostiles, par exemple pour des câbles sous-marins. La fibre guide d'onde optique à l'âme segmentée présente une dispersion totale négative sur la fenêtre opérationnelle variant entre 1530nm et 1570nm environ, ce qui permet d'empêcher toute formation de solitons. Les propriétés les plus importantes, à savoir la dispersion nulle, la longueur d'onde de coupure, l'atténuation, et la résistance à la courbure, se situent en outre à l'intérieur d'une certaine gamme. Le guide d'onde de cette invention présente également une distorsion modale faible polarisation.
