非线性光学（NLO）薄膜的极化是构建基于电光聚合物的调制器的重要步骤。本文采用标准超大规模集成制造工艺设计和制造了一种基于分散红1(DR1)侧链聚甲基丙烯酸甲酯(PMMA/DR1)非线性光学薄膜的电光调制器。讨论了极化方法，采用接触极化对非线性光学薄膜进行极化。极化电压通过击穿电压的测量来确定。给出接触极化之前和之后折射率发生变化。得到12pm/V的电光系数。
Poling of nonlinear optical (NLO) film is an important step in building an electro-optic polymer-based modulator. In this paper, an electro-optic modulator based on disperse red 1(DR1) side chained poly(methyl methacrylate) (PMMA/DR1) nonlinear optical film is designed and fabricated using the standard very large scale integration fabrication procedures. The poling methods are discussed and the contact poling is used to poling the nonlinear optical film. The poling voltage is determined by the measurement of break- down voltage. The refractive indices change before and after contact poling is given. The electro-optical coefficient of 12pm/V is obtained.
