Chiral organic polymers doped with or appended by nonlinear optical dyes aredisclosed. The use of chiral polymers produces a more stablenoncentrosymmetricenvironment for the dye molecules resulting in unexpectedly long relaxationtimes ascompared with previously used organic polymers. In addition, the NLO/chiralpolymermaterials exhibit high electro-optical coefficients (r33), high nonlinearoptical coefficients(d33), improved long-term thermal stability, and at the same time retain theprocessingadvantages associated with organic polymers. Thus, the present NLO/chiralpolymermaterials are extremely well-suited for use in second-order nonlinear opticalandoptoelectronics devices.
