Optical coupling between laser wave-guides and optical fiber

Hello Everyone,

First of all, I am a beginner to use this software and getting to know this from the tutorials posted. I am trying to model 'Optical coupling between laser wave-guides and optical fiber'. I am curious to know whether there are any pre-defined templates for optical fiber and laser wave-guides. If no, can any one help me how to build those ones in the COMSOL software. It would be of great help if anyone give a thumbs-up.

Thanks in advance.

Regards,
