HELLO RANJEET..
As explained in the post by Damian that the lightwave analyzer can be set to different input/output configurations depending on what you would like to do. You could for example set it to output an optical signal and read in an optical signal to find the frequency response of the RSOA. Using the component properties window you can set the characteristics of the laser and the frequencies to sweep in your simulation. The global parameter “Iterations” will set the number of frequency data points used.
Kindly refer to the link…it will help u definitely..
Thanks and regards
