Abstract
An optical component mounting substrate which comprises grooves for holding optical fibers, other grooves for optical components being inserted and optical waveguides is produced with a press molding process. A mold having convex and/or concave surface profiles which are corresponding to the grooves and the optical waveguides to be formed on a surface of the optical component mounting substrate is used as a die in the press molding process. The surface profiles of the mold are precisely transferred onto the surface of a transparent glass base substrate, thereby forming the optical component mounting substrate having a desired surface configuration including the grooves and the optical waveguides. Optical fibers are aligned along the grooves and fixed by a light-curing adhesive. Since a press molding process is applied, the optical component mounting substrate can be produced easily at a low cost with mass production and also can attain many advantages such as small coupling loss, small crosstalk, high positional accuracy, excellent reproducibility and high reliability.
