Corrugation width of Bragg gratings based on the coupling coeffecient


#1

I’m simulating a silicon waveguide Bragg gratings, is there a way to know the coupling coeffecient and then calculate the corrugation width of each grating ?

Thank you

Hi,

There is a KB article that mentions coupling coefficient and corrugation depth, if this is what you are looking for?
