PROBLEM TO BE SOLVED: To decrease the number of components and to facilitate the assembly by fixing a light emitting element component or light receiving element component in a hole bored in a housing wall positioned on a line at the tip of a branch-side waveguide. SOLUTION: The light receiving element 13 and light emitting element components 14 to 16 are fixed at specific positions in a hole of the right wall of a housing respectively. Then an optical receptacle 12 is inserted into a hole of the left wall of the housing 1, an optical waveguide 11 is arranged in the housing, and those are held on an optical stage. Then light is guided in from the optical receptacle 12 and the light receiving element 13 is used as a monitor to obtain an optical receptacle 12 where the optical waveguide 11 and optical receptacle 12 are fixed. Then while the output light from the optical receptacle 12 is guided to an optical power meter, the light emitting element 14 is placed in operation, the optical axes of the light emitting element 14 and one tip of the branch waveguide are aligned with each other, and the optical receptacle 12 is adhered and fixed to the left wall part of the housing 1 at an optimum position. |
