<p>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 area 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.</p> |
