Patent

CA 2300225

Chiral organic polymers doped with or appended by nonlinear optical dyes are disclosed. The use of chiral polymers produces a more stable noncentrosymmetric environment for the dye molecules resulting in unexpectedly long relaxation times as compared with previously used organic polymers. In addition, the NLO/chiral polymer materials exhibit high electro-optical coefficients (r33), high nonlinear optical coefficients (d33), improved long-term thermal stability, and at the same time retain the processing advantages associated with organic polymers. Thus, the present NLO/chiral polymer materials are extremely well-suited for use in second-order nonlinear optical and optoelectronics devices.
