报道了一种用于测量聚合物非线性光学薄膜高阶折射率的电光测量技术。评估的基础是通过实验中的直流和交流调制电场分离线性和二次电光效应。该方法通过未极化和极化聚合物膜的结果进行了验证。
An electro‐optic measuring technique is reported by which higher‐order susceptibilities of nonlinear optical polymer films can be determined. The basis of the evaluation is the separation of linear and quadratic electro‐optic effects by means of a dc and ac modulated electric field in the experiment. The method is demonstrated with results for an unpoled and a poled polymer film.
