Dear All,
I would like to simulate beam divergence from the linear fibre bundle, which includes 7 small circular fibres (200um core diameter, NA 0.22).
I have tried the Source Ellipse, with the given core diameter, by changing the values for Gx and Gy I see that the beam charges from collimating to diverging. But there I am not sure how to calculate the values for the Gx and Gy.
How to set the NA in Source Ellipse? Which type of source can I choose from NSQ, that I can set the core diameter and NA?
Thanks in advance.
