    • A nonlinear optical interpenetrating polymer network which can exhibit nonlinear optical properties includes a first polymer, and a second polymer interpenetrating the first polymer. At least one of the polymers includes a nonlinear optical component. A method of forming a nonlinear optical interpenetrating polymer network which can exhibit nonlinear optical properties includes combining a first prepolymer, which can react to form a first polymer, with at least one monomer which can react to form a second polymer. At least one of either the first prepolymer or the monomer include a nonlinear optical component. The nonlinear optical component is poled and the first prepolymer and the monomer, or monomers, of the second prepolymer are reacted while the nonlinear optical component is being poled. The reaction of the first prepolymer forms a first polymer network and reaction of the monomer(s) form a second polymer network which interpenetrates the first polymer network to form an interpenetrating polymer network. The interpenetrating polymer network fixes the nonlinear optical component in the poled position, thereby forming an interpenetrating polymer network which exhibits nonlinear optical properties.
    • 可以显示非线性光学性质的非线性光学互穿聚合物网络包括第一聚合物和互穿第一聚合物的第二聚合物。 聚合物中的至少一种包括非线性光学部件。 形成可显示非线性光学性质的非线性光学互穿聚合物网络的方法包括将可与反应形成第一聚合物的第一预聚物与至少一种可反应形成第二聚合物的单体组合。 第一预聚物或单体中的至少一种包括非线性光学组分。 非线性光学部件被极化,并且第二预聚物的第一预聚物和单体或单体在非线性光学部件被极化的同时反应。 第一预聚物的反应形成第一聚合物网络,并且单体的反应形成第二聚合物网络,其互穿第一聚合物网络以形成互穿聚合物网络。 互穿聚合物网络将非线性光学部件固定在极化位置,从而形成呈现非线性光学性质的互穿聚合物网络。
