ABSTRACT:
The present invention relates to an optical waveguide substrate, realized by means of a simple configuration and processes, having a structure in which an optical component can be embedded within an optical waveguide layer composed of resin, and a structure in which the surface of the optical waveguide layer can be made flat, as well as a method of fabricating the same. The optical waveguide substrate comprises a substrate, first and second core portions, extending in directions which intersect on the substrate; and an optical component having a reflecting surface which reflects light propagating through one of the first and second core portions toward the other. The optical waveguide layer has first and second supporting portions which hold the optical component while sandwiching it. These first and second supporting portions are composed of the same respective materials as the first and second core portions, and are formed on the main surface of the substrate together with the first and second core portions. The optical component as well as the first and second core portions are covered with a cladding portion.
