摘要

研制了一种基于交流调制Senarmont补偿器的电光表征装置，该装置特别适合于研究聚合物薄膜的电光响应。该系统能够测量各种波长的波克尔效应，最小相移灵敏度为1 μ rad。样品间系数测量的变化小于15%。对共面电极上的薄极化电光聚合物薄膜进行了系统的评价，以证明该装置的实用性，并对外加电场的边缘效应进行了修正。电光数据的再现性通过对聚合物厚度依赖性的检验得到了验证

An electro-optic measurement apparatus for organic media

An electro-optic characterization apparatus based on an AC modulated Senarmont compensator, which is particularly suited for studying the electro-optic response of thin polymer films, has been developed. The system is capable of measuring the Pockel's effect at a variety of wavelengths with a minimum phase-shift sensitivity of 1 mu rad. Sample to sample variations in the coefficient measurements are less than 15%. A systematic evaluation of thin, poled electro-optic polymer films on coplanar electrodes has been made to demonstrate the usefulness of the apparatus, Corrections are described for the fringing effects of the applied electric field. The reproducibility of the electro-optic data has been verified through an examination of the polymer thickness dependence.<>
