集总型电极光波导调制器的研究

A Research on Lumped Electrode Optical Waveguide Modulator

光波导调制器是光纤通信系统中的重要器件．本文分析了Ｍ－Ｚ（即Ｍａｃｈ－ｚｅｈｎｄｅｒ）干涉型光波导调制器的工作原理，研究了集总参数型电极的频宽特性，在ＬｉＮｂＯ３基片上用导波技术设计、制作了光波导调制器，并测量了主要性能．

Optical waveguide modulator is an important device in optical fiber communication. This paper describes the operation mechanism of the M--Z interferometric modulator,analyses the frequency band characteristics, designs and fabricates optical waveguide modulator and measures the main parameters of the modulator.
