Patent number: 5982969Abstract: In an optical transmission tube comprising a tubular cladding and a core within the cladding having a higher index of refraction than the cladding, a strip-shaped reflecting layer is longitudinally extended between the cladding and the core. Light passing through the core is reflected and scattered by the reflecting layer to emerge from the tube through an area of the outer surface of the cladding opposed to the reflecting layer. The optical transmission tube is prepared by dispersing scattering particles in a monomer solution; filling a tubular cladding with the monomer solution; resting the cladding horizontally for allowing the scattering particles to settle on a lower inner surface of the cladding; and thereafter, causing the monomer solution to polymerize and solidify within the cladding.Type: GrantFiled: April 24, 1998Date of Patent: November 9, 1999Assignee: Bridgestone CorporationInventors: Hideo Sugiyama, Masato Sugimachi, Minoru Ishiharada, Yasuhiro Morimura, Tatsuo Terahama, Hiroshi Fukuyama, Itsuo Tanuma

Patent number: 5684913Abstract: The invention relates to an optical waveguide tube comprising a tubular cladding filled with a solid core having a higher refractive index than the cladding. In one form, a resin material having a Tg of up to 50.degree. C. and a modulus of elasticity of up to 10.sup.9 dyne/cm.sup.2 is used as the core.
