  这是频率监视器的数据
  这是模式扩展监视器设置
  run后模式扩展监视器任何一个数据都打不开是为什么呢

  你好，你的这个模型的波导部分是上方那个细的光栅耦合器嘛？它的光传播方向应该沿着波导方向，然后你的profile monitor 和mode expasion monitor 要垂直于波导截面，并且它们的中心要完全一致。
  另外你可以看看这个例子https://optics.ansys.com/hc/en-us/articles/360034902433

  感谢回复，这是一个光栅耦合器。mode expansion monitor就是垂直于波导截面的（2D X-normal）。我放置了两个这样的监视器，TM的可以打开并看到数据，但TE的在visualize mode data时出现如下错误

  你这应该是因为光源入射方向的问题，导致这个器件对TE模式没有耦合，你可以用profile监视器看看场。
