    摘要： In an optical waveguide comprising a transparent cladding (1) filled with a transparent liquid core (2) having a higher refractive index than the cladding, a liquid consisting of an oligomer having a phosphazene skeleton, typically phosphazene oil is used as the core (2). The waveguide is well resistant to heat and weathering, ensures stable performance in a wide temperature range over a long period of time, and provides good light transmission in a wide wavelength range covering the UV, visible and IR spectra.

    摘要： An optical waveguide hose includes a hollow tubular cladding made of a material having rubber elasticity at the service temperature of -50.degree. to 150.degree. C. and having a lower creep. The cladding is filled with a core fluid having a higher index of refraction than the cladding and closed with sealing plugs at opposed open ends. The hose is improved in flexibility and handling, prevents gas penetration into the core fluid, maintains transparency at widely varying temperature over a long time, and is lightweight and inexpensive.

    摘要： 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. In another form, a copolymer of acrylic acid, methacrylic acid or a lower alcohol ester thereof with a higher alkyl (meth)acrylate is used as the core, preferably in combination with a phosphate, aromatic carboxylate, aliphatic carboxylic acid, aliphatic carboxylate or glycol. In a third form, such an optical waveguide tube is prepared by filling a hollow tubular transparent cladding having opposite open ends with a liquid monomeric charge and causing the monomeric charge to polymerize while pressurizing the exposed surfaces of the monomeric charge inwardly from the opposite open ends along an axial direction of the cladding, thereby forming a core within the cladding.
