Abstract
An optical fiber interconnecting structure for connecting an optical fiber to an optical channel waveguide, in which a channel waveguide is extended collinearly by a hollow channel with sectional area and shape substantially identical to those for the channel waveguide. An optical fiber is laid collinearly with the channel, and a core-extension is formed at the end facet of the optical fiber to form a gradual and smooth optical transition to the channel waveguide. 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.
