  • Patent number: 8073295
    Abstract: A material for an optical circuit-electrical circuit mixedly mounting substrate comprises a light permeable resin layer, and an optical circuit forming layer that is made of a light permeable resin of which refractive index increases (or decreases) when irradiated with an activating energy beam and is disposed adjacent to the light permeable resin layer, wherein a refractive index of a portion of the optical circuit forming layer is higher (or lower) than that of the light permeable resin layer when the material for the optical circuit-electrical circuit mixedly mounting substrate is irradiated with an activating energy beam so that said portion is irradiated.

  • Patent number: 7989148
    Abstract: In a method for forming a photoelectric composite board (10) on which a photoelectric transducer (5) is mounted, photo-masks (111, 112, 113) which are used in processes to form the photoelectric composite board (10) are respectively disposed on the basis of a reference mark (33) previously formed on a metal thin film (101). In addition, openings (22) are formed on solder resist layers (8) by irradiating laser beams at positions defined on the basis of a reference point (4a) defined above a light deflector (4) formed on an end of a light guide (3).

  • Patent number: 7967663
    Abstract: A process of forming a deflection mirror in a light waveguide with a use of a dicing blade having a cutting end with a flat top cutting face and at least one slanted side cutting face. The process includes a cutting step of cutting a surface of the light waveguide to a depth not greater than a width of the flat top cutting face, thereby forming a groove in the surface of the light waveguide. The groove has a slanted surface which is formed by the slanted cutting face to define the deflection mirror in the waveguide.
