TY - JOUR A1 - Goldenberg, Leonid A1 - Köhler, Mathias A1 - Kahle, Olaf A1 - Dreyer, Christian T1 - Impact of inorganic nanoparticles on optical properties of low refractive index waveguiding polymers TI - Optical Materials Express N2 - The objective of this work is to improve the optical properties of low refractive index polymers used for waveguide by introduction of inorganic nanoparticles. Copolymers of fluorinated monomers and glycidyl methacrylate are used. Introduction of SiO2 nanoparticles into polymer matrix is performed by direct mixing; copolymerization with SiO2 nanoparticles modified by monomer, and in situ sol-gel formation of SiO2 during photochemical cross-linking and annealing catalyzed by photoacid generator. It is demonstrated that nanoparticles are able to decrease thermo-optic coefficient. It is also possible to fabricate waveguiding layers by direct introduction of nanoparticles without compromising of optical propagation losses.
