Claims
- 1. A process for switching or modulating light transmission which comprises introducing an incident fundamental light frequency into a transparent optical medium which is comprised of a composite composition consisting of an inorganic oxide glass monolith with a microporous structure containing an incorporated solution comprising a solvent component and an organic component which exhibits nonlinear optical response, and the glass monolith microporous structure has pore diameters in the range between about 15-2000 angstroms, and all of the pore diameters are within about a 100 angstrom diameter variation range.
- 2. A process in accordance with claim 1 wherein the organic component is a thermoplastic polymer which is characterized by a recurring monomeric unit corresponding to the formula: ##STR8## where P' is a polymer main chain unit; m is an integer of at least 3; S' is a flexible spacer group having a linear chain length of between about 1-25 atoms; X is --NR--, --O-- or --S--; R is hydrogen or a C.sub.1 -C.sub.4 alkyl group; Y is ##STR9## and Z is an electron-donating group or an electron-withdrawing group; and wherein the glass monolith has sealed outer surfaces, and the glass monolith microporous structure has pore diameters in the range between about 15-2000 angstroms, and all of the pore diameters are within about a 100 angstrom diameter variation range.
- 3. A process in accordance with claim 2 wherein the optical medium polymer is characterized by an external field-induced orientation of aligned polymer side chains.
- 4. A process in accordance with claim 1 wherein the organic component is a thermoplastic polymer which is characterized by a recurring monomeric unit corresponding to the formula: ##STR10## where m.sup.1 is an integer of at least 5; n is an integer between about 2-20; X.sup.1 is --NR.sup.1, --O-- or --S--; R.sup.1 is hydrogen or methyl; and Z.sup.1 is --NO.sub.2, --CN or --CF.sub.3 ; and wherein the glass monolith has sealed outer surfaces, and the glass monolith microporous structure has pore diameters in the range between about 15-2000 angstroms, and all of the pore diameters are within about a 100 angstrom diameter variation range.
- 5. A process in accordance with claim 4 wherein the optical medium polymer is characterized by an external field-induced orientation of aligned polymer side chains.
