Abstract:
1. An optical waveguide module comprising: a wiring board in which electrical wiring is formed on at least one surface; a light-receiving element that is mounted on said wiring board such that the light-receiving region is arranged to face the surface on which said electrical wiring has been formed; and an optical waveguide substrate on which an optical waveguide has been formed that is positioned on the opposite side from said light-receiving element with said wiring board interposed; wherein a base member of said wiring board has transparency with respect to light of the wavelength that can be received by said light-receiving element; a wavelength filter for reflecting light of wavelengths other than the wavelength that can be received by said light-receiving element, is arranged between said base member of said wiring board and said optical waveguide; an aperture is formed in said electrical wiring at a position that faces said light-receiving region of said light-receiving element, this aperture being larger than the contour of the core of said optical waveguide; and the end of said optical waveguide of said optical waveguide substrate and said light-receiving region of said light-receiving element are optically coupled through said wavelength filter and said aperture.
