1. An optical fiber mounting waveguide device, comprising:

  • a substrate;

    an optical fiber mounting groove provided on a part of the substrate for mounting an optical fiber;

    an under cladding layer and a core sequentially formed on the substrate; and

    an over cladding layer formed on the core, the over cladding layer having an end surface facing to the optical fiber mounting groove,wherein the core and the under cladding layer are protruded toward the optical fiber mounting groove with respect to the end surface of the over cladding layer, andwherein an end surface of the core protrudes with respect to the end surface of the over cladding layer, and the end surface of the core and the end surface of the over cladding layer are provided on different planes.
