Hello.

I have a problem about the optical modulator measured element in Lumerical Interconnect. I want to design an asymmetric mach-Zehnder Interferometer and use an optical modulator conncted to DC source to make length difference between two arms. Despite of voltage change in DC source, I never see any shift in optical transmission and, all transmission spectra Vs. frequency or free spectral range are the same. How can I solve this problem and make one phase controbale mach-zehnder circuit? I attach the diagram of my design in interconnect for more detail? Thanks.

Hello Are you using Optical modulator element ? Most likely its not modulating phase wit DC input. can you please chek, the voltage in DC source. If the modulator isn't configured properly (e.g., missing Vπ, length).

Can you povide screenshot of properies of OM1 and DC-1?

Thanks

Hello.

Thanks so musch for your attention. I attach the properties of two options you want. Alternatively, I used the N-port S-parameter element instead of splitter element, and then enter our s-matrix obtained from MMI simulation. Fortunately, this showed clear change in transmission spectrum. But I do'nt know this process is correct or not. That's kind of you if you bring me a solution in order to use these results in the next MODE solution simulation.

Thanks for sharing the screenshot.
It looks like you're heading in the right direction.

I’m a bit unclear about this part: "That's kind of you if you bring me a solution in order to use these results in the next MODE solution simulation."
Could you clarify what you mean? Also, have you already extracted the S-parameters from MODE?
