Abstract: A method of preparing a sol-gel material is described. A metal alkoxide and an organically modified Si-alkoxide having a predetermined functional group are dissolved in a first solvent and a second solvent to form a first solution and a second solution, respectively. The first solution and the second solution are then mixed and heated. As a result, the metal alkoxide reacts with the organically modified Si-alkoxide, and a functionalized sol-gel material is formed thereby. Furthermore, the solid content of the functionalized sol-gel material is increased by transferring the same into another solvent. Therefore, a thick sol-gel film is fabricated by means of the transferred functionalized sol-gel material.

Abstract: The present invention relates to a glass article for use as an optical waveguide fiber and more particularly to an optical waveguide fiber, the core of which is doped with a chalcogenide element to significantly increase the refractive index of the core. The subject of this invention is novel doped silica core compositions wherein a portion of the oxygen in the silica is replaced with either sulfur, selenium or tellurium using plasma enhanced chemical vapor deposition (PECVD). These compositions are designed to have higher refractive indices than silica, low coefficients of expansion, high optical transparency, and appropriate viscosity and softening points to make them ideal candidates for use as optical waveguide fibers.
