ELECTROOPTIC POLYMER OPTIMIZING FOR STABL E ORGANIC ACTIVE COMPONENTS

Major performances have been achieved with organic materials to build electro-optical components such as phase or amplitude modulators. But the main bridle of their development is the unstability of the Pockels effect caused by the relaxation of the poled molecular groups grafted on a polymer matrix. We present here a method to overcome the disadva ntage based on the synthesis of a new polymer family, which keeps a go od electro-optic coefficient until 85-degrees-C without depletion at t his temperature for a long time.
