Abstract
The invention relates to optically transmissive, silica-containing compositions which exhibit a small change of refractive index with respect to temperature changes (dn.sub.g /dT). The compositions are derived from silica sols dispersed in liquid organic polymers. The invention relates to optical systems comprising a plurality of elements that are optically interconnected by means of the inventive composition. An especially preferred embodiment of the invention is the use of the composition within a connector to simultaneously align and join optical fibers.
