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 nonliner optical response.
Claims4
In an optical light switch or light modulator device the improvement which comprises an optical medium element comprising a composite composition consisting of an inorganic oxide glass monolith with a microporous structure containing an organic component which exhibits nonlinear optical response;
- wherein the glass monolith microporous structure has an average pore diameter in the range between about 50-300 angstroms, and substantially all of the pores in the microporous structure have diameters within about 100 angstroms diameter variation range.
In a process for switching or modulating light transmission the improvement which comprises introducing an incident fundamental light frequency into a switching or modulating transparent optical medium which is comprised of a composite composition consisting of an inorganic oxide glass monolith with microporous structure containing an organic component with exhibits nonlinear optical response;
- wherein the glass monolith microporous structure has an average pore diameter in the range between about 50-300 angstroms, and substantially all of the pores in the microporous structure have diameters within about a 100 angstrom diameter variation range.
