中文摘要：

电光调制器作为光通信系统中最重要的器件之一,其性能决定了光通信系统的传输性能,而电光调制器的电极结构、种类和设计都对调制器的性能有重要的影响。针对基于光纤布拉格光栅（FBG）的新型电光调制器电极展开了研究和设计,并通过数值计算方法,对模场重叠因子、电极结构参数以及模场重叠因子和FBG中心波长漂移量的关系做了讨论,并由此对基于FBG的聚合物电光调制器的电极做了一系列的分析和研究。文中的研究对基于FBG的电光调制器的制作具有一定的指导意义,能够促进电光调制器的发展。

英文摘要：

Electro-optic modulator is one of the most important components for optical communication system. Its performance determines the transmission performance of an optical communication system. For the electrode, its structures, species and designs have a significant influence on the property of modulator.For designing and researching the electrode of novel electro-optic modulator based on FBG, the relationship among the overlap of mode field, structural parameters of electrode and FBG＇s center wavelength shift Δλ were discussed in this paper by numerical calculation methods. It has a significance of manufacture of polymer electro-optic modulators based on FBG, and promotes the development of electro-optic modulator.
