Thanks for your reply.
Enclosed is setup for my simulation to getting to know how to use this visualizer and measure the bandwidth of RSOA.
I give an electrical signal to directly modulate the RSOA at 1GHz and 2GHz. So i set the start frequency and stop frequency at 1 GHz and 2 GHz, use an E-O operation. I meanwhile set the iteration in global parameter to 2 as you said. But i am not sure the bitrate here in global parameters is 1 or 2? Or arbitrary value since the operation frequency is managed by start/stop frequency rather than this parameter?
I think i have correctly connect all the components but the result seems…
So could you help me in this example?
