How to implement finite rejection ratio notch filter in INTERCONNECT?

      Hi,

      how can I implement a finite rejection ratio optical notch filter in INTERCONNECT? Do you have any suggestions on how to model the rejection ratio? My setup is as shown on the picture. Thanks.

      Hi, I don't think there is a built-in element in the Element Library that will do this. You will have to create a custom element with S-parameters. The best way to do this is probably with a Scripted Element that uses the setsparameter command. The "Frequency Dependent Transmission" element in the "scripted_elements.icp" file on the Scripted Element page uses this approach. You can use this to set the amplitude of the S-parameters to match the amplitudes of your filter.
