More Information
Summary:An optical waveguide having means for performing optical coupling with high efficiency at a predetermined position in an optical circuit substrate and which optionally includes an optical-electrical circuit board. Also provided are an optical waveguide, an optical path thereof being changed in an optical circuit at a steep angle and the optical waveguide for performing coupling and splitting of light being decreased in size in the optical circuit. The optical waveguide has a core and a cladding layer, and a wall surface, which is formed by cutting out at least a part of the core in a thicknessdirection of the core through irradiation of a laser beam and crosses at least a part of the core, which is a specular surface.
