[求助]用ZEMAX计算光纤的耦合效率 [复制链接]

我用ZEMAX计算光纤的耦合效率，可是我发现当接收光纤的数值孔径增大时耦合效率反而降低了，这是怎么回事呢？

我也想知道，同问，呵呵

我是新手也想知道对于光耦合的问题

有没有这方面的书籍？

The system efficiency is the fraction of the energy in the source 0SziTM  
beam that exits the optical system. This value is determined by V qW(S1w

The receiver efficiency is the fraction of the transmitted energy U= PG0

The coupling efficiency is the fraction of energy radiated v2Bks2

数值孔径不是越大越好呀,当耦合光学系统的模式与你光线的模式完全匹配时,耦合效率最大. |3MqAvPJ  
耦合效率的计算有一个积分过程,还是比较复杂的.

            

能否请问五楼的大侠怎么做到的，谢谢啊~~335797507@qq.com
