Hello everyone,
I hope this message finds you well.
I tried to get a spectrum of the second-order grating. I tried changing all the parameters, but I still couldn’t see any reflection from the second-order grating. I select in Grating definition: Order 2, and no matter what I do, I can’t get a spectrum of the second-order grating. Does anyone know how to solve this problem? Could someone suggest the parameters of any grating and fiber for which second-order diffraction will work?
