摘要
本文介绍一种新颖的无损伤检测技术——连续波电光检测技术(OWEOP)对LiNbO_3定向耦合波导调制器模拟样品内场分布进行各种测量所获得的实验结果。采取了背射和端射两种测量方式,测出了波导电极条下,电极间隙区以及电极中断区电场的分布,并对实验结果进行了讨论。
This paper Introduces the application of CWEOP (continuous wave electro-optic probing) technique in the measurements of electric field distributions in the samples of LiNbO3 directional coupling waveguide modulator. Two configurations of
measurement——the backside incidence and the end incidence have been taken in
the experiments. The curves of electric field distribution under the electrodes, and in the region between two eleotrods and in the in terrupt region of electrodes have been obtained. The experimental results have been discussed.
