相干光源

      老师您好,

      请问FDTD中如果用多个光源,要是单波长的话,它们之间是相干的吗?

      需要多个相干光源的时候必须要加入功率分配器件一起仿真吗?

      FDTD中光源都是相干的!

      你要想一想用多个相干光源的物理意义,和软件能否实现,比如,两束分别以正负30度入射的平面波可以形成干涉,但是因此此时需要用Bloch边界仿真,因此单个仿真就不能同时用它们两个,需要分别做两个仿真,最后通过后续处理得到想要的结果,前提是你知道如何做后续处理,即明白其物理意义和数学公式。

      当然,不同单波长在一些非线性仿真中是可以用的。https://optics.ansys.com/hc/en-us/articles/360043165194-Nonlinear-optics-list-of-examples
