Coupling efficiency

Please login with a confirmed email address before reporting spam

I'm pretty new to comsol and did most of the optical ray tracing tutorials.

My challange is to calculate the light/photon coupling efficyncy in a pmma fiber. I started with a light source and a pmma fiber, on 2 cm distance. with air in between. but i wont get the result i expect. can someone help me with the constraints of the source and the cable?
