The organic polymers are very promising materials for the thermo-optic modulators because they exhibit one order larger magnitude in thermo-optic coefficient than silica. However, there are several problems for the polymer to be solved such as optical loss and thermal and optical stability. In this work we have prepared UV-curable organic materials derived from cyclic siloxanes substituted with perfluoro-polyalkylether-acrylate in order to have low optical loss and high thermal stability. NMR and Mass spectroscopy confirmed the successful synthesis of the product. Transparent and stable films were obtained from the product by photo-curing, which was optimized by FT-IR investigation. The cured polymer films showed 1.39 of refractive index, -1.59 × 10-4 of thermo-optic coefficient, 0.0002 of birefringence, and 0.1 dB/cm of optical loss, which were measured by prism coupler at 1550 nm of laser source.
