Overlap integral calculation for a directional coupler

Please login with a confirmed email address before reporting spam

Hello Everyone,

I am new to comsol. I am learning comsol with best of my ability to implement a directional coupler model and calculate coupling co-efficient from the overlap integral expression given in the screen shot.

I built two soultions, one is the single mode fiber and other one is the hollow core fiber and I need to find the coupling co-efficient "kappa". Please let me know how can I implement given integral expression using normalized fields from two of these solutions.

Your valuable suggestions would be highly appreciated. Thanks
