Subscriber我在一篇论文中看到光束质量对输出效率有影响,想要仿真不同M2情况下输出光的情况。
计算可知M2=1.3时对应LP01:LP11=1:0.1941,但我对应FDTD的光源设置不太了解,感觉自己只能挑选给定的TE和TM,想问一下,如何设置才能让光源发出我想要的光呢。
纤芯和包层折射率分别为1.4682和1.4629

Ansys Employee遗憾的是,光束质量是结果,不是因,同一个M2对应的高斯光束可以很不同(主要指尺寸)。 在给定波导情况下,你是无法改变其模式的所谓光束质量的。你只能选择不同的模式来仿真。April 20, 2022 at 9:17 am652921049
Subscriber谢谢你的回复,那么仿真时是怎样根据仿真结果得到光束质量的呢

Ansys Employee光束质量是计算出来的,不是仿真出来的。你可以搜一下网上的说明。应该是先给出一定形状的光束,计算其光束质量M2,再仿真。Viewing 6 reply threads- The topic ‘给定光束质量,FDTD中光源如何设置?’ is closed to new replies.
