The polymers for an optical waveguide must meet a number of different demands such as low optical loss at the telecommunication wavelength, adjustable refractive index, thermal and photochemical stability. In this work we have prepared UV-curable polymeric materials based on multifunctional siloxane group containing perfluoropolyether structure to meet the properties. The siloxane perfluoroalkyl groups are expected to promise better transparency in the optical wavelength and thermal stability. Perfluoropolyether structure with hydroxyl as one end and allyl as the other was prepared by reaction between fluorinated diols and allyl bromide. Then it was reacted with cyclic siloxane with platinum catalyst in a fairly high yield. The terminal hydroxyl was converted to acryl by reaction with acryloyl chloride. Transparent and stable films were obtained from the acryl product by UV irradiation. The polymer films showed 1.39 of refractive index, 0.0002 of birefregence, and 0.1 dB/cm of optical loss, which were measured by prism coupler at 1550 nm of laser source.
