[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 J[?7`6\M  
beam that exits the optical system. This value is determined by >_<J=8|E  
the input na, entrance pupil size and position, apodization, oD0N<Ln}  
transmission of the optics, and vignetting. =` %iv|>r0

The receiver efficiency is the fraction of the transmitted energy Py3Y*YP  
that couples from the exit pupil to the receiving fiber. This k *#fN(_  
value is determined by aberrations and the na of the receiving fiber. ~kkwPs2V

The coupling efficiency is the fraction of energy radiated Y(`# J[  
by the source that couples into the receiver. This is the Z6`oGFq  
product of the system and receiver efficiencies. =>_k;x

The maximum efficiency is the coupling efficiency if there 1l~(J:DT

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. mHnHB.OL  
耦合效率的计算有一个积分过程,还是比较复杂的.
