| 摘要 |
The present invention relates to fabricating an optimal sheet material for optical waveguide use. In this optical waveguide sheet material, optical waveguide fibers that are constituted by cores and cladding in a plastic sheet base material pass through the sheet material in the direction of thickness of the sheet material, and moreover, a plurality of optical waveguide fibers are arranged parallel to each other. The method of fabricating this sheet material includes steps of forming a plurality of optical waveguide fibers as a bundle by fusion-bonding or pressure-bonding using a plastic base material, and then forming a sheet by cutting this bundle of optical waveguide fibers such that the surface of the sheet is orthogonal to the fiber direction of the optical waveguide fibers. |
