Abstract : This invention relates to acrylic polymers and more specifically to polyacrylamides and polyacrylates such as poly(2-N-2-methyl-5-nitrophenylamino)ethyl acrylate and poly(N-2-methyl-4-nitrophenyl) acrylamide. These acrylic polymers are particularly useful as nonlinear optical components in various electrical devices for processing optical signals including interferometers, optical switches, optical amplifiers, generators, computational devices and the like. This invention relates to acrylic polymers and more specifically to polyacrylamides and polyacrylates capable of exhibiting nonlinear optical responses in an electric or electromagnetic field. Specifically, this invention is directed to the use of these acrylic polymers as the nonlinear optical component in various electrical devices for purposes of processing optical signals. Recent developments have led to increased use of optical components in various electrical and optoelectronic devices, i.e. devices containing optical components which either active or passive components. These devices include, for example, the use of optical materials in second harmonic generators, modulators e.g. spatial light modulators, phase shifters, optical amplifiers, laser technology, interferometers, optical switches. logic gates, communications and computational devices, and alike. It is generally known that various organic compounds and particularly polymeric materials can exhibits nonlinear optical responses which in some instances is larger tha some of the inorganic materials.
