Multimode Waveguides

The fabrication of single and multimode waveguides and optical characteristics were investigated. The singlemode waveguide was fabricated by a laser direct writing technique and a multimode waveguide was produced by means of a direct UV patterning technique using organic-inorganic hybrid materials. The fabrication of waveguide channels with these techniques are of interest for simple processes. The resulting single and multimode waveguides exhibited a near rectangular shape and low optical loss. The average propagation losses of these waveguides were 0.07 dB/cm (at 850 nm) and 0.3 dB/cm (at 1310 nm), respectively.

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‥
