I would really appreciate your help.
I am trying to simulate a ring resonator with out-coupled gratings on top, and excuse me for being new to Lumerical, but I have no idea how to make the gratings to bend about the ring, maintaining a position in the centre of the ring.
I tried to do this with just a few small gratings, and after adding sources and the like, I still get this error:
I defined my own materials (as n,k materials), and here is the view of the gratings (I just put a few since I got tired of copy pasting and wanted to find a better, more automated way of getting the gratings about the ring):
I am at a loss…no idea how to approach this problem. I would GREATLY appreciate any help.
Thank you so much.
