Abstract
An optical waveguide module according to the present invention comprises an optical waveguide substrate having an optical waveguide formed therein, an optical waveguide holder for mounting the optical waveguide substrate thereon, an optical fiber connector supporting an optical fiber therein, and an optical fiber holder for mounting the optical fiber connector thereon, the end faces of the optical waveguide holder and the optical fiber holder are brought into contact with each other while aligning the optical waveguide and the optical fiber, the end faces of the optical waveguide substrate and the optical fiber connector are bonded at least partially through a gap, and a hardening matching agent having a refractive index matching with those of the optical waveguide and the optical fiber is filled in the gap. Therefore, the optical waveguide and the optical fiber do not wear out or are damaged when alignment is performed, and stable coupling characteristics between the optical waveguide and the optical fiber can be obtained by the sufficiently filled hardening matching agent.
