摘要

本文提出利用共面微屏蔽线实现新型结构的铌酸锂光调制器，并利用保角变换的方法计算该结构调制器的特性阻抗、等效折射率、调制带宽．并根据此计算结果算出所需的调制电压．结果表明利用该结构有效地减小了调制器的速度失配、增加了调制带宽，是一种可行性的方案，本文并根据计算结果填充了较理想的调制器的尺寸大小．

Abstract

A LiNbO3 optical modulator with coplanar microshield line is discussed. The characteristic impedance

effective index and available bandwidth of the modulator have been derived by conformal mapping.According to theses results

the needed modulating voltage is presented. These numerical results show that this structure effectively decreases velocity-mismatching between optical wave and microwave and increases the modulation bandwidth.
