I’m a beginner at Lumerical and have been attempting to model the ring resonator used in the following paper.
I have used both FDTD and Mode in an attempt to replicate the paper’s results. I have only been trying to replicate the results shown in figure 1b, the transmission spectrum of a typical silicon ring resonator as used in the experiment.
However, my simulated resonator is not achieving full coupling. I have examined my simulation’s outputs in multiple ways, including S-Parameters and DTF monitors. My exported S-Parameters are generally flat lines and do not reflect the expected output.
I have followed Lumerical tutorials on ring resonators and had no trouble achieving expected results in them.
I’m curious if the issue I’m having is related to light Modes. The paper says that TM mode is used and that is what I set my ports to, but is there more that I need to do?
Any help would be appreciated. Thanks.
