  • Silicon-containing networked non-linear optical compositions
    Patent number: 5433895
    Abstract: A nonlinear optical composition and a method of forming the nonlinear optical composition are disclosed. The nonlinear optical composition includes a silicon-containing component and a nonlinear optical component which causes the nonlinear optical composition to exhibit second order nonlinear optical polarization of electromagnetic radiation, such as light. The method includes forming a sol of the silicon-containing component and the nonlinear optical component of the composition. A gel is formed from the sol. The nonlinear optical component is then poled while the gel is exposed to conditions sufficient to cause formation of a nonlinear optical composition which exhibits second order nonlinear optical polarization of electromagnetic radiation.
