On the Lumerical website, it gives an equation for the time signal of standard source, but says “Note: There are some small difference between the pulse generated by this code and the actual time signal generated by the ‘standard’ source pulse setting.” I wonder what the differences are.
Also, for the broadband source, it says “Note: The ‘broadband’ option is generated with a more complex function. The precise function is not provide.” I wonder if this information definitely cannot be revealed to the users.
I understand that we can do custom time signal, but I haven’t had much success with it. And even if I did have success, I would like to compare with Lumerical’s time signal. So I would really want to know the exact equations of the time signal set by Lumerical.
Thank you very much.
