摘　　要：应用ANSYS公司的HFSS和Designer对一种内嵌共面波导电极结构的聚合物电光调制器进行了协同仿真,设计出了带宽为56 GHz的聚合物电光调制器。通过对光波有效折射率和微波有效折射率的优化,实现了速度匹配。同时利用协同仿真方法对电极进行了优化设计,实现了阻抗匹配并降低了微波损耗。结果表明应用协同仿真方法可以提高计算效率,有助于对各种结构的行波电极进行优化。A method which combines HFSS software with designer high frequency circuit to co-simulate a electro optical pol ymer modulator with a in-plane coplanar waveguide electrode is proposed in this paper. A bandwidth of 56 GHz electro-optic polymer modulator is designed. First, the effective refractive index of light and microwave is optimized to meet the velocity matching. Then, the microwave characteristics of the electrode system are analyzed by co-simulation method to meet the impendent matching and lower microwave propagating loss. The results show that the co-simulation method can improve corn putational efficiency. And it is contributive tO optimize a variety structure of traveling-wave electrode.
