<p><P>PROBLEM TO BE SOLVED: To provide optical path converting parts, in which high density packaging and reduction in the size are achieved, packaging of an optoelectronic element is easily conducted with low coupling loss and reliability is made high, and to provide an optical surface mounted waveguide using the parts. <P>SOLUTION: A core 3 of the transmission path of the optical path converting part has a light beam incident port 5, a light emitting port 6 and a reflection surface 4. The portions excluding the ports 5 and 6 and the surface 4 are covered by clad 2 having a refractive index lower than that of the core 3. An optical path of light beams is converted to have a prescribed angle using reflection at the surface 4. The refractive indexes of the core of the transmission path and the clad are matched with the refractive indexes of the core of the optical wavegudie and the clad. Hole spaces 47 are formed at prescribed positions of the optical waveguide, the optical path converting part is buried and an optoelectronic element is packaged on the top section. <P>COPYRIGHT: (C)2004,JPO</p> |
