Abstract
Abstract This invention provides an optical medium which consists of an inorganic glass monolith with a microporous structure containing an organic component which exhibits nonlinear optical response. In one embodiment this invention provides a sol-gel process for producing a composite of a transparent homogeneous microporous inorganic oxide glass monolith and an organic compound which exhibits nonlinear optical response.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
80 words
A process for producing a composite composition comprising a homogeneous inorganic oxide glass monolith with a microporous structure containing an organic component which exhibits nonlinear optical response, which comprises hydrolyzing tetraalkoxysilane under acidic or basic pH conditions in a sol-gel reaction medium comprising water, a water-miscible organic solvent and an organic component which exhibits nonlinear optical response, until gellation of the reaction medium is completed, and removing the solvent medium to provide a porous glass monolith with incorporated organic component.
Claim 2
Dependent Claim
80 words
A process for producing a composite composition comprising a homogeneous inorganic oxide glass monolith with a microporous structure containing an organic component which exhibits nonlinear optical response, which comprises hydrolyzing tetraalkoxysilane under acidic or basic pH conditions in a sol-gel reaction medium comprising water, a water-miscible organic solvent and an organic component which exhibits nonlinear optical response, until gellation of the reaction medium is completed, and removing the solvent medium to provide a porous glass monolith with incorporated organic component.
Claim 3
Dependent Claim
27 words
A process in accordance with claim 1 wherein substantially all of the pores in the microporous structure have diameters within about a 100 angstrom diameter variation range.
Claim 4
Dependent Claim
13 words
A composite composition produced in accordance with the sol-gel process of claim 1.
Claim 5
Dependent Claim
85 words
A process for producing a composite composition comprising an inorganic oxide glass monolith with a microporous structure containing an organic component which exhibits nonlinear optical response, which comprises (1) hydrolyzing tetraalkoxysilane under acidic or basic pH conditions in a sol-gel reaction medium comprising water and a water-miscible organic solvent component until gellation of the reaction medium is completed; (2) removing the solvent medium to provide a porous glass monolith; and (3) impregnating the porous glass monolith with an organic component which exhibits nonlinear optical response.
