    • 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.
    • 本发明提供了一种具有足够的厚度的非线性光学元件,其可以用作不易破裂的薄膜及其制备方法。 提供了一种对入射光产生非线性响应的新型非线性光学元件,其包括半导体或金属的细碎晶粒,该晶粒已经通过含有所述官能团的基质形成物质中的官能团的反应分离出来, 分散在矩阵中。 还提供了一种制备对入射光具有非线性响应的非线性光学元件的方法,其包括将含有官能团的基质形成物质与金属,半导体或其前体的溶液混合,形成 然后使所述官能团进行反应以形成基质,同时允许所述金属或半导体的细碎颗粒在所述基质中分离出来。
