Reply To: Coupling issue between a source (Gaussian) and circular Bragg grating (CBG)

Hi Rezoana,

It seems to me more like a theoretical issue. I believe it will depend upon your geometry and the specific light-matter interactions that will take place. You can run a simulation for different distances and see how the coupling efficiency changes. Or maybe you could also try setting up an optimization task with the distance as a parameter within a specific range and the coupling efficiency as the objective function to determine what would be the best distance.
