    Abstract: A method that provides a new way to embed rare earth fluorides into silicate (or germania-doped silica) glasses by means of solution chemistry. Embedding rare earth fluorides into a silicate (or germania-doped silica) glass comprises the following steps. First, form a porous silicate core preform. Second, submerge the preform into an aqueous solution of rare earth ions. Third, remove the preform from the solution and wash the outside surfaces of the preform. Fourth, submerge the preform into an aqueous solution of a fluorinating agent to precipitate rare earth trifluorides from the solution and deposit in the pores or on the wall of the preform. This is followed by drying.

    Abstract: A gradient-index optical element comprises SiO2, BaO, and TiO2 as essential components, and has a refractive index profile in its diametrical direction. The molar ratio of barium to silicon at the center of the element in its diametrical direction is limited to Ba/Si≧0.4. This gradient-index optical element has a small refractive index difference with reduced chromatic aberrations and, hence, is suitable for use with optical equipment.
