I would like to evaluate the performance of the MZI-based EO modulator by utilizing Lumerical's interconnect. (The parameter of TW electrode was extracted through HFSS of ANSYS.)

However, in the example provided, there were many explanations for the EYE diagram, but no explanations were found for how to obtain the EO bandwidth.

However, I found a similar file utilizing impulse response in the example of ring modulator, but it didn't work well in my case. (I had a problem where the bandwidth changes every time I change the sample rate)

So I'd like to know how to get EO bandwidth from EO modulator in general.
