I have designed an MRR, where I used ONA for output nature prediction.
I have applied X mode from ONA then a splitter is used for X and Y mode and then I combine X and Y, for input in MRR, then my question is-

  1. I want to check in output that, what I am getting X or Y mode (TE or TM)? How I can judge whether TE or TM is obtained at output ports. please solve 1.icp (1.0 MB)
