关于EME设置衬底的问题

    • Shu Lin

      如果多模干涉耦合器基于蓝宝石上硅(SOS)设计,那么EME的background material该如何设置?

      蓝宝石上硅需要BOX为AL2O3且上包层为Air

      是直接将参数background material设置为AL2O3,还是设置为Air然后另外设置一个BOX结构?

      蓝宝石上硅需要BOX为AL2O3且上包层为Air,是不是理解为

      AL2O3-蓝宝石-硅-AL2O3-Air?

      你可以同background material设置为AL2O3,但是空气部分需要另外添加;

      或者background material设置为空气,另外加两个AL2O3。

      背景材料就是没有其它材料的地方所用的缺省材料。

        结构是这样的,那就是可以background material设置为空气,然后在硅MMI下面加一层Al2O3这样对吗

      对,Al2O3作为基底,Air作为包层。
