Hi, I want to plot the transmission vs round trip loss in the ring resonators, with and without graphene on the ring. Please suggest me approach to do that. I am using the following example as reference.

transmission vs round trip loss？
I believe you can plot transmission vs wavelength/frequency, or some kind of loss vs wavelength/frequency. Or trasmission vs coupling gap etc.

I want to plot a graph similar to above for our own designed structure. I want to study the effect of geometrical parameters of the ring on the coupling i.e. over-coupling, under-coupling and critically-coupling. On the x-axis, it says resonator round trip loss. This round trip loss is loss after the wave transfers the one full round of the circumference. The loss can also be tuned by applying the voltage to the graphene layer transferred onto the circumference of the ring. The y-axis plots the transmission into the bus waveguide. Please suggest how to approach to measure such losses using FDTD or MODE Solver.
The picture is taken from the following article (Fig. 1c). https://doi.org/10.1515/nanoph-2020-0363

"The loss can also be tuned by applying the voltage to the graphene layer transferred onto the circumference of the ring. "
This sentence is important! Basically the round trip loss is controlled by external votage to alter the refractive index. therefore you will need to change the refractive index (may also has material loss) to get the above curves.
You will need to have an expression for the round-trip loss before you can calculated. From what I found you may be able to get this from the transmission. However different autors may have a little different assumption. Please find the paper's definition.
