【Abstract】 A novel three dimensional electro optic polymer containing photo crosslinkable group was synthesized. 4 Nitroaniline and cinnamyl were introduced onto the polymer matrix of bis A epoxy as the electro optic chromophore and photosensitive chromophore respectively. A thermal stable polymeric electro optic film was prepared by spin coating, followed by the corona poling and photo crosslinking reaction in the late poling phase. An external electro optic measuring system based on the electro optic film was fabricated, by which the electric signals propagating on the coplanar waveguide were measured.更多还原
