To fabricate a (110) silicon hard master, we used anisotropic wet etching. The etching chemical for the silicon wafer was a TMAH 25% solution. We fabricated a 1x4 multimode planar waveguide splitter using the silicon hard master. Organic-inorganic hybrid materials were used as core and cladding layers of the planar waveguide splitter. The 15 μm-thick under-cladding layer was coated on a silicon substrate and baked. After the core layer was coated on the under-cladding layer, the core pattern was formed by using a hot embossing process at 100 °C and 1-3 kg/cm2. The propagation loss of the planar waveguide was 0.4 dB/cm and the insertion loss of the 1x4 planar waveguide splitter was 11.2 dB at the total splitter length of 3.5 cm.

This work successfully prepared an UV curable organic-inorganic hybrid material consisting of organic modified colloidal silica. Applications of UV curable organic-inorganic hybrid materials include abrasion resistant coatings, photo-patternable thin films and waveguides. Colloidal silica containing reactive functional groups were also prepared by reacting organic silane and tetraethyl orthosilicate (TEOS) using sol-gel process. In addition, the efficiency of grafting organic moiety onto silica nanoparticles was investigated by applying TGA and FTIR techniques. Experimental results indicated a strong interdependence between surface modification efficiency and solution pH. Acrylate-SiO2 hybrid formation could result in a shifting of thermal degradation temperature of organic component from about 200°C to near 400°C. In addition, the stability of organic modified colloidal silica in UV curable formula and the physical properties of resulting coatings were discussed. Furthermore, the morphology of organic modified colloidal silica was investigated by performing TEM and SEM studies‥
