Normalized Spectrum Response

[Umar]

Hello ! I am simulating Spectrum Response and got result (attached). Can anyone guide me how to get smoother results? as this result contain a lot of variations. Which parameter is required to modify to get desired result.

where is the results and the system ?

For first sight, I think it might be correct.
I are doing phase modulation so that would make the spectrum has abrupt changes as you see. if you check the OSCilloscope output, you will see the phase changes based on you input signals.

hope that helps,
thanks

Thank you for reply @Mohamed Actually I am trying to implement microwave photonic filter the results attached on paper are in normalized format (attached in red colour according to selected wavelength). however the filter notch in mine simulation have at same place as stated in paper but with varriations. So as a beginner I am trying to overcome the mentioned problem.

1 more thing, is it possible to generate impulse in order to check response of microwave photonic filter? or another way is available to find the filter response.
Regards
