摘要：PROBLEM TO BE SOLVED: To provide an optical multiplexing waveguide that makes reduction of leaked light possible in a merging section and that needs no extension of a waveguide length. SOLUTION: The optical multiplexing waveguide is provided with two optical waveguides 31, 32 on the input side and one optical waveguide 33 on the output side that is merged into the optical waveguides 31, 32. The optical waveguide 32 on the input side is coupled with the end of the optical waveguide 33 on the output side in a coupling section 35, while the optical waveguide 31 on the input side is coupled with an inner part from the end of the optical waveguide 33 on the output side in a coupling section 34. The two optical waveguides 31, 32 on the input side can each employ an S-shaped bend waveguide which is formed by coupling two circular arcuate shapes in point symmetry, wherein the radius of curvature of the optical waveguide 32 is made smaller than that of the optical waveguide 31.
