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．
An electrode of an electro-optic modulator using an organic polymer (Polym er) as an optical waveguide was designed. Through theoretical derivation and computer aided numerical calculation of the electrode characteristic impedance and conductor loss factor, and their relationship with the electrode width, height, thickness. The influence of the variation of electrode width, height and thickness on the characteristic impedance and conductor loss factor and the influence of conductor loss on the modulation bandwidth were analyzed. The frequency response of Polym er optical waveguide modulator was simulated. The frequency response curve shows that the ultimate bandwidth of the electrode is above 100 GHz.
