An optical fiber interconnecting structure connects an optical fiber (5) to an optical channel waveguide (1), in which a channel waveguide (1) is extended collinearly by a hollow channel (2) with sectional and shape substantially identical to those for the channel waveguide (1). An optical fiber (5) is laid collinearly with the channel (1), and a core-extension (6) is formed at the end facet of the optical fiber (5) to form a gradual and smooth optical transition to the channel waveguide (1). The channel waveguide may be tapered out to have a substantially larger sectional area at the far end so as to ease the optical interconnection.

Une structure interconnectant des fibres optiques raccorde une fibre optique (5) à un guide d'onde (1) à canal optique. Ce guide d'onde à canal optique (1) est prolongé de façon colinéaire par un canal creux (2) de largeur et de forme pratiquement identiques à celles du canal optique (1). Une fibre optique (5) est placée en colinéarité avec le canal optique (1), et une extension de la partie centrale (6) est formée sur la facette terminale de la fibre optique (5) afin de créer une transition optique graduelle et lisse vers le guide d'onde à canal optique (1). Le guide d'onde à canal optique peut être terminé en pointe de façon à avoir une section transversale sensiblement plus large à l'autre extrémité afin de faciliter l'interconnexion optique.
