New Method of Designing Broad Band Waveguide Electrooptic Modulator

介绍一种用于计算、设计宽带波导电光调制器的新方法．用该方法对波导电光调制器进行数值计算，得到了电光调制器电极产生的电场分布，器件的特征阻抗，并优化设计出带宽可达８．１ＧＨｚ·ｃｍ和特征阻抗为５０Ω的宽带波导电光调制器．

A new effective method for calculating and designing a broad band waveguide electrooptic modulator is introduced.By using this method the electric field distribution and the characteristic impedance of the modulator are obtained,and an optimistically designed broad band waveguide electrooptic modulator with about 8 GHz bandwidth and 50 Ω characteristic impedance is given.
