ABSTRACT:
Non linear optical compositions contain a vinylidene fluoride copolymer and an additive having molecular optoelelectronic activity, e.g. methyl-N-(2,4-dinitrophenyl)-alaninate. Poled films derived from the composite display optoelectronic activity. There is a marked contrast with known techniques in which single crystals are utilized. The compositions are used to make laminates which display good waveguide properties.
