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 |

20110110623 | OPTICAL WAVEGUIDE FILM, LAMINATED TYPE OPTICAL WAVEGUIDE FILM, OPTICAL WAVEGUIDE, OPTICAL WAVEGUIDE ASSEMBLY, OPTICAL WIRING LINE, OPTICAL/ELECTRICAL COMBINATION SUBSTRATE AND ELECTRONIC DEVICE - An optical waveguide film includes at least one optical waveguide area having an X-direction and a Y-direction orthogonal to the X-direction. Such an optical waveguide film includes a plurality of core portions arranged side by side within the same layer so as to extend along the X-direction, each of the core portions having side surfaces, and the core portions adjoining to each other in the Y-direction being arranged through a gap therebetween; and a plurality of cladding portions provided so as to cover the side surfaces of each of the core portions, each of the cladding portions formed of a resin having an optical refractive index smaller than that of each of the core portions, and the cladding portion between the adjoining core portions providing each gap. In the optical waveguide film, a size of the gap between the adjoining core portions varies along the X-direction in at least a part of the optical waveguide area. This makes it possible to precisely match a gap between core portions in a cut end surface with a desired value by selection of cutting positions of the optical waveguide film even when the optical waveguide film is shrunken. | 05-12-2011 |
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 |
20110243499 | OPTICAL WAVEGUIDE AND OPTICAL WAVEGUIDE MANUFACTURING MEMBER - An optical waveguide includes a clad layer, a core layer and a clad layer which are laminated together in this order from a lower side thereof. Within the core layer, a core portion and a side clad portion provided adjacent to the core portion so as to surround side surfaces of the core portion are formed. Further, a part of the side clad portion prevents a left side end of the core portion from being exposed outside. A mirror formation region is constituted from a region consisting of such a part of the side clad portion and a part of each of the clad layers located thereabove and therebelow. This mirror formation region is subjected to digging processing so that a concave portion is formed. An inner surface of this concave portion serves as the mirror. From the mirror, a material other than a material constituting the core portion, that is, a material constituting each of the clad layers and a material constituting the side clad portion are exposed. | 10-06-2011 |
