Reply To: MZI EO modulator – how to get EO bandwidth?

[Dev]

Hello, Aplologies for the delay in response.

If the sample rate is high enough, the bandwidth shouldn't change much when increasing the sample rate.

So the reason for your simulation have noticeble change is because of small sample rate. Sometimes a high sample rate is required to get a good digital filter fit. 

You can try increasing the sample rate further to see how much the results changes.

Let me know if the issue is solved or further assistance required. 

Thanks and regards
