Dear Alistu, in my case also the LASER spectrum comes like as you have attached in the above reply when I copy and paste all the components in a new project file and run the simulation and get the output at the optical spectrum visualizer, but what may be the problem in the file I have attached in reply #25355. But copy paste all the components should not be a solution. It should be possible solve the problem in the same layout Either by changing the layout parameter or by changing the component property, if my attached file is running properly in your system, Then there may be some problem with my system also.
If anyone is facing the same problem with me please let me know.
With regards
