ABSTRACT:
This invention provides nonlinear optical media which have a stable noncentrosymmetric array of side chain polymer molecules, such as an electric field poled and stabilized medium of a 50/50 copolymer of N-methyl-4-[2-(4-nitrophenyl)ethenyl]phenylamino-2-ethyl 2-methyl-2-propenoate and 4-[2-(4-nitrophenyl)ethyenyl]phenylthio-2-ethyl 2-methyl-2-propenoate.
