摘要
从电极设计的角度对行波电吸收调制器(TW-EAM)的带宽进行分析,用一个共面波导的TW-EAM的测量数据进行设计计算演示,介绍了本设计方法的计算过程.计算演示结果与实验测量结果相吻合.文章还分析了中间电极宽度和电极间距对带宽的影响.并简单说明用它计算设计的一个GaAs/GaAlAs多量子阱(MQWS)TW-EAM获得大带宽的例子.
Abstract
The bandwidth of the coplanar traveling-wave electroabsorption modulator(TW-EAM) was analyzed in the aspect of designing electrode. The calculation process of this method was introduced by demostrating designing a coplanar TW-EAM with its measured data. The demostrating result tallies with the result of experimental measure. It was analyzed the effect of the width of middle electrode and the electrode interval on the bandwidth. An example is also introduced that a GaAs/GaAlAs multiple quantum wells(MQWs) TW-EAM with alarge bandwidth which was designed by using this method.
