【摘要】 设计了以有机聚合物（Ｐｏｌｙｍ ｅｒ）作为光波导的电光调制器的电极．通过理论推导和计算机辅助数值计算得出电极的特征阻抗和导体损耗系数，以及它们与电极的宽度、高度、厚度之间的关系．分析了电极宽度、高度、厚度的变化对特征阻抗和导体损耗系数的影响，以及导体损耗对调制带宽的影响，并模拟了Ｐｏｌｙｍ ｅｒ光波导调制器的频率响应．通过频率响应曲线得知电极的极限带宽在１００ ＧＨｚ以上．更多还原

【Abstract】 This paper putem phasis on researching and designing the electrodeofan electroopticm odulator ofpolym eropticalw aveguide. The two im portantparam eters——characteristic im pedance and coefficient ofconductorloss w ere discussed. The influence on the tw o param eters, which is caused by the change of height, width, and thickness ofthe electrode, was analysed w ith the theoreticaldeviation and com puter aided num ericalcalculation. Atlast, the frequency response curve ofpolym er optic waveguide m odulator w as given by com puter sim ulation.更多还原
