Abstract
Interference filters which are optical components are erected in advance on optical paths in a transparent container, and the transparent container is filled with a photo-curable resin solution. Further, a jig is prepared for manufacturing an optical waveguide device. The jig includes a housing, and holes. On this occasion, positions of the holes are set such that light input through the hole reaches the holes via the interference filters. Optical fibers are fitted into the holes of the housing and the housing is mounted on the transparent container. Next, light at a predetermined wavelength is guided into the optical fibers so that optical waveguides are formed in the photo-curable resin solution. Next, the photo-curable resin solution is exchanged for a low-refractive-index photo-curable resin solution and then the low-refractive-index photo-curable resin solution is solidified wholly by ultraviolet light. Finally, for example, an optical fiber, a light-receiving element, etc. are provided.
