Abstract
Described herein are photo-patternable sol-gel precursors and their methods of preparation. The sol-gel precursors are thermally stable and form compositions that have high refractive indices and low optical loss values. The precursors can be used to make sol-gel compositions that are ideally suited toward optical waveguide applications in the realm of telecommunications wavelengths.
