Abstract
The present invention provides a nonlinear optical element having a sufficient thickness that can be used as a thin film insusceptible to crack and a process for the preparation thereof. A novel nonlinear optical element which gives a nonlinear response to incident light is provided, comprising finely divided grains of a semiconductor or metal, which grains have been separated out with the reaction of a functional group in a matrix-forming substance containing said functional group, dispersed in a matrix. A process for the preparation of a nonlinear optical element which gives a nonlinear response to incident light is also provided, which comprises mixing a solution of a matrix-forming substance containing a functional group with a metal, a semiconductor or a precursor thereof to form a uniform solution, and then allowing said functional group to undergo reaction to form a matrix while allowing finely divided grains of said metal or semiconductor to be separated out in said matrix.
