Hi all,

A simulation that requires the coupling of the output of a RC telescope to a single mode fiber. But, I am facing a problem while analyzing the coupling efficiency. The coupling efficiency is analyzed by using FICL operand and the single-mode coupling in the analyze tab. The results obtained are  different in the two cases. Both the analysis is done by ignoring the source fiber and only the numerical aperture of receiver fiber is considered.  Any help towards this will be appreciated. 

Thank you. Looking forward to your reply.
