Polymeric electro-optic materials and devices: meeting the challenges of practical applications

Practical applications of electro-optic polymers require thermally stable materials with high electro-optic coefficients and low absorption loss. In this report ,we first review the properties of some azo-based electro-optic polymer materials and devices. We then describe a new class of electro-optic cardo polymers with glass transition temperatures greater than 200°C.
