Reply To: Electrostatic simulations of a modulator

[Ruzan Sokhoyan]

Regarding the example of the Mach Zender interferometer, I indeed see the slight asymmetry in the electric field distribution at 0 V and 6.5 V. Do you think this asymmetry is physical or a result of the numerical error? As seen above, this asymmetry becomes very dramatic when the silicon pad is replaced with a dielectric material with the same DC permittivity. Why is there such a dramatic difference between results observed in the two simulation setups?
