20090148096 | OPTICAL INTERCONNECTION DEVICE - An optical interconnection device is provided. The optical interconnection device includes an optical component and a substrate on which the optical component is surface-mounted. The substrate includes: an optical waveguide which is formed in the substrate and which includes a core layer, and a cladding layer covering the core layer; and an optical path changing portion provided adjacent to one end portion of the optical waveguide to change an optical path of light transmitted through the optical waveguide or an optical path of light communicated by the optical component. A width of the core layer is broadened toward the optical path changing portion, when viewed from a plane which is parallel with a surface of the substrate. | 06-11-2009 |
20100109173 | METHOD OF MANUFACTURING OPTICAL WAVEGUIDE - An optical waveguide is cut by moving a heated knife blade across the optical waveguide with the knife blade maintained at a predetermined angle. At that time, by maintaining the temperature of the knife blade at a temperature not lower than the glass transition point of the optical waveguide, a portion, in contact with a bevel plane of the knife blade, of the optical waveguide softens to be planarized along the bevel plane. In this way, an optical path conversion mirror constituted of a planarized cut plane is formed in a region through which the bevel plane has passed. | 05-06-2010 |
20100316343 | OPTICAL WAVEGUIDE AND METHOD OF MANUFACTURING THE SAME, AND OPTICAL WAVEGUIDE MOUNTED BOARD - A first clad layer is formed on a first substrate, and further first cores extending in parallel to each other in one direction are formed on the first clad layer. Separately from this, a second clad layer is formed on a second substrate, and further second cores extending in parallel to each other in a direction parallel to the first cores are formed on the second clad layer. Next, the first substrate and the second substrate are integrated with a third clad layer interposed therebetween in such a manner that a surface of the first substrate having the first cores formed thereon faces a surface of the second substrate having the second cores formed thereon, to thereby form an optical waveguide. | 12-16-2010 |
20110129182 | OPTICAL WAVEGUIDE DEVICE AND METHOD OF MANUFACTURING THE SAME - An optical waveguide device includes a wiring substrate, an optical waveguide bonded on the wiring substrate and having a light path conversion inclined surface on both ends, and a light path conversion mirror formed to contact the light path conversion inclined surface of the optical waveguide and formed of a light reflective resin layer or a metal paste layer. In case the light reflective resin layer is used as the light path conversion mirror, the light reflective resin layer may be formed partially only on the side of the light path conversion inclined surface, or may be formed on the whole of the wiring substrate to coat the optical waveguide. | 06-02-2011 |
