Recently I have learned about the ring resonator example on your website.But I have some question whci I dont understand and want to ask.
In fact I dont understand why a channel spacing of 200GHz means 1.6nm at 1550nm,the how to get the FSR from 3200GHz and how to get the Q value from it.
Secondly, I have download the resonator file including VarFDTD and FDTD file,I change the parameter value of both the two file, but I get different results,which is shown below.
I dont know what make the two results different.Can you help me check it. Thanks a lot.
