在官方的例程中,如 edge coupler,仿真光纤到波导的耦合效率时,port 勾选了 USE FULL SIMULATION SPAN,但为了精确得到耦合到波导的能量,是不是应该取消勾选 USE FULL SIMULATION SPAN,然后将 port 的尺寸尽可能设置与波导尺寸相仿?

当然可以,只是这样的话横向尺寸大,需要更多内存很更长仿真时间。

好的,但是现在遇到的问题是,如果我勾选了 USE FULL SIMULATION SPAN,我的|S^21|^2 耦合效率为 90%,但是如果我取消勾选,将尺寸缩小到与波导尺寸相近,耦合效率只有 10%,是不是意味着我的能量大部分是在包层里。

你可能需要检查:
1: 两个Port模式是否正确
2:用Profile监视器看看是否泄露。
我估计例子那样设置原因可能有几个,比如保证仅使用所需要的模式,内存需要小等。
