Abstract
Abstract This invention provides an optical medium which consists of a composite of a homogeneous inorganic oxide glass monolith with a microporous structure containing a liquid crystalline polymer component. In one embodient this invention provides a sol-gel process for producing a composite of a transparent homogeneous microporous inorganic oxide glass monolith and a liquid crystalline polymer.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
82 words
In an electrooptic light switch or light modulator device the improvement which comprises an optical medium component which is a composite composition of a homogeneous inorganic oxide glass monolith produced by a sol-gel process, with a microporous structure having a content of a liquid crystalline polymer; wherein the glass monolith microporous structure has pore diameters in the range between about 15-2000 angstroms, and substantially all of the pores in the microporous structures have diameters within about a 100 angstrom diameter variation range.
