Ansys Employee首先,如果是均匀弯曲,即相同的球面半径,完全不需要计算每个地方的neff,它们是一样的!
“为什么入射角theta改变的话,入射方向上的mode source的面积就会变化呢?当theta接近90度时,面积几乎变为0了,此时看到的模式也变得非常奇怪。请问有什么办法能正常计算出此时的neff呢;
这是因为你确定的截面错了!超过45度后应该将Injection Axis换为水平的。你试一下看看。
这种情况下需要勾选bent waveguide选项并设置吗?似乎没有mode source里面bent waveguide的使用说明,勾选它也看不见类似FDE里面那种圆的图示。 当然,如果不勾选,那就认为是直波导:
可能需要时间琢磨一下,模式光源与FDE是一样的,只不过FDE功能更多,模式光源用的就是FDE。Viewing 1 reply thread- You must be logged in to reply to this topic.
