| 摘要 |
The present invention relates to an optical waveguide device, particularly a structure for positioning end faces of an optical waveguide and end faces of optical fibers with respect to each other, as well as a method of realizing such a structure. V grooves for positioning optical fibers are formed on a glass substrate by hot pressing, and the optical fibers are put in the V grooves to position end faces of the optical fibers and end faces of an optical waveguide with respect to each other, thereby forming the optical waveguide device of the invention.
