I'm trying to extract the change in the loss value that appears as I control the width of the waveguide.



The loss values derived by moving the width directly [object tree -> edit object] from the basic setting (boundary condition = PML) [run -> eigensolver analysis -> calculate mode],

and the loss values derived by setting [sweep -> edit -> parameter waveguide width setting -> result] is markedly different.



I think setting conditions are needed to match this, but I can't find it, so I'm asking you a question.

I would appreciate it if you could let me know why the two loss values are derived differently and how I can match them.

 

Thank you.

Hi Juhee,

I assume you are using FDE to calculate the lossed in both cases (sweep and manually changing the parameters). Are you tracking the losses linked to a specific mode? If you are using the same simulation to do both, I don't think we should be seeing discrepancy. How different are they?
