Abstract
A method for the preparation of silicate glasses of controlled index of refraction involves the thermal and/or plasma processing of organo-silicon polymers. Compositions so treated evidence a suppressed index of refraction which may subsequently be increased by sintering to yield a material uniquely suited for use in fiber optic devices.
