Patent ID: 6932880

Claim:
A method of manufacturing an optical waveguide device provided with an optical waveguide, said optical waveguide being continuously formed by curing a first photo-curable resin in a direction of an optical axis with light of a predetermined wavelength guided into said first photo-curable resin liquid, wherein said method comprises: preparing an optical fiber for guiding said light into a box of said optical waveguide device filled with said first photo-curable resin liquid, and fixing said optical fiber to said box; curing said first photo-curable resin liquid along an optical path of said light by said light outputted from said optical fiber, and making a forward end of said optical path abut on said box to thereby fix a forward end of said cured first photo-curable resin liquid to said box; thereafter, removing an uncured portion of said first photo-curable resin liquid from said box; and filling said box with a second photo-curable resin liquid, and curing said second photo-curable resin liquid so that said cured second photo-curable resin liquid has a refractive index lower than that of said cured first photo-curable resin liquid, wherein at least one retention member transparent or reflective to said light is provided in said box in a state that said retention member is fixed to said box, so that said optical waveguide is bonded to said retention member when said first photo-curable resin liquid is cured.
