电光（EO）聚合物膜的电光系数r33的值取决于在电极化过程之后实现的偏振密度。本文报道了一种高温液体接触极化方法，在LD-3EO聚合物薄膜中获得了高达250 V/μm的极化电场，且表面损伤较小。在633 nm处测得的r33值为18 pm/V，比先前报道的数据高40°/V。这样的高极化场和因此更大的r33值通过接触极化或电晕极化都不能实现。
The value of electro-optic coefficient r33 of an electro-optic (EO) polymer film depends on the polarization density achieved after the electric poling process. In this letter, we report a high temperature liquid contact poling method which provides a poling field as high as 250 V/μm in LD-3 EO polymer film with less surface damages. The r33 value was measured to be 18 pm/V at 633 nm which is 40°/V higher than the previous reported datum. Such a high poling field and therefore larger r33 value are not achievable through either contact poling or corona poling.
