Abstract
An optical module may include precise guide pins formed in a transparent substrate or an optical transmission line support member. The precise guide pins may be inserted into corresponding precise guide holes within the transparent substrate or the optical transmission line support member to precisely align optical elements. The precise guide holes may be formed within one of the transparent substrate and the optical transmission line support member by positioning protruding portions of a jig within over-sized guide holes and filling a gap between the protruding portions of the jig and the respective over-sized guide holes with a filler material. Once the filler material is cured, the jig may be withdrawn leaving precisely positioned guide holes.
