We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

I am not sure what kind of symmetry you expect: between two contacts? it is less likely, since the potential is gradually reduced to drive the current. Please test this example  and see if the static field is symmetric: https://optics.ansys.com/hc/en-us/articles/360042327854-PIN-Mach-Zehnder-modulator

You may check result at zero voltage and compare it with higher voltage.
