Abstract
An optical waveguide having stable low branching ratio is disclosed, which includes a primary optical waveguide portion coupled at a input end thereof to an input-side optical fiber. branched optical waveguide portions each having one end continuously connected to a output end of the primary optical waveguide portion and the other ends coupled to a plurality of output-side optical fibers and an introductory waveguide portion coupled to the input end of the primary optical waveguide portion and having a width substantially identical with a core diameter of the input-side optical fiber. Further, there is provided a method of producing an optical branching device in which the optical waveguide is formed.
