| 20090245720 | OPTICAL ELEMENT MOUNTING BOARD, OPTICAL CIRCUIT BOARD AND OPTICAL ELEMENT MOUNTING BOARD - A substrate on which an optical element is mounted is provided, including: an optical element; an optical circuit substrate which is formed by an optical waveguide layer having a core portion and cladding portions; and an electrical circuit substrate on which is provided a mounting portion that is used for mounting the optical element, wherein the optical element is mounted on the electrical circuit substrate via the optical circuit substrate and wherein the optical circuit substrate has an optical element mounted thereon and is provided with a receptor structure having a conductive portion that conducts electricity between an electrode of the optical element and an electrode of the electrical circuit substrate. | 10-01-2009 |
| 20100226606 | SUBSTRATE FOR MOUNTING AN OPTICAL ELEMENT, OPTICAL CIRCUIT SUBSTRATE, AND SUBSTRATE ON WHICH AN OPTICAL ELEMENT IS MOUNTED - A substrate on which an optical element is mounted is provided, including: an optical element; an optical circuit substrate which is formed by an optical waveguide layer having a core portion and cladding portions; and an electrical circuit substrate on which is provided a mounting portion that is used for mounting the optical element, wherein the optical element is mounted on the electrical circuit substrate via the optical circuit substrate and wherein the optical circuit substrate has an optical element mounted thereon and is provided with a receptor structure having a conductive portion that conducts electricity between an electrode of the optical element and an electrode of the electrical circuit substrate. | 09-09-2010 |
| 20110085771 | ELECTRONIC APPARATUS, CELLULAR PHONE, FLEXIBLE CABLE AND METHOD FOR MANUFACTURING OPTICAL WAVEGUIDE FORMING BODY - According to the electronic apparatus and cellular phone of the present invention, in an optical waveguide forming body of a flexible cable, an air layer is provided in a deforming section which experiences bending deformation as a result of the movement of a second body relative to a first body (either a pivoting or sliding movement), and the position of this air layer becomes located on the outer circumferential side of a core when the deforming section undergoes bending deformation. As a result of this, it is possible to ensure sufficient flexibility and to also achieve a sufficient improvement in the folding endurance of the core portion for this optical waveguide forming body to be utilized in practical applications. Moreover, it is possible to suppress light loss and achieve high-speed, large-capacity transmissions even when the optical waveguide forming body of a flexible cable experiences bending deformation due to the relative movement of the second body relative to the first body. | 04-14-2011 |

| 20110158596 | OPTICAL WAVEGUIDE, OPTICAL WIRING LINE, OPTICAL/ELECTRICAL COMBINATION SUBSTRATE AND ELECTRONIC DEVICE - An optical waveguide is provided. The optical waveguide includes a plurality of core portions and a plurality of clad portions in which each core portion being provided between a pair of clad portions. Each of the plurality of clad portions comprises: a low refractive-index area being in contact with the core portion, wherein a refractive index of the low refractive-index area is lower than that of the plurality of core portions; and a plurality of high refractive-index areas separated from the core portion through the low refractive-index area, wherein a refractive index of the plurality of high refractive-index areas is higher than the refractive index of the low refractive-index area. The plurality of high refractive-index areas are provided in the clad portion in an aligned manner or in a scattered manner. The plurality of high refractive-index areas are constituted of the same kind of material as a constituent material of the plurality of core portions. The plurality of high refractive-index areas make light scattered. Such light does not enter the plurality of core portions and involuntarily enters the plurality of clad portions. By doing so, it is possible to prevent the light from reaching light receiving elements, so that it is possible to improve quality of optical communications. | 06-30-2011 |
