      I used INTERCONNECT to stimulate single bus ring

      HiShelley ,nFor this case of transmission, please make sure you use the peak at maximum to be false so that it measures the peak at the minimum transmission instead of maximum transmission. In this case the transmission at the maximum is pretty flat so it is hard to decide where is the peak. Please give it a try and let me know.n

      nHi GWANG,nThank you! I have solved this question in this transmission by your method.n But when I change a parameter to get a new transmission, I meet a new problem.nThere is a warning that Insufficient number of peaks detected to calculate free spectral range.nThe FSR is 0:nnquality factor is a point :nnI decrease the pit excursion from 7 to 3nThe problem still exists.nCan you tell me how to solve this problem?n

      In addition, when I change the peak at maximum from false to true, the warning is vanishes. nBut According the transmission, the FSR may be right and the quality factor is wrong.ntransmission :nFSR:nquality factor :nn

      HiShelley,I believe this is because the peaks are below the threshold to be detected. You may want to play around with the peak threshold and peak excursion values to make this work. The definition for the parameters are in this page:https://support.lumerical.com/hc/en-us/articles/360036617973.n
