The interferometer structure considers a highly-doped Si-based waveguide that can control the phase shift byvarying the refractive index through the carrier concentration while applying a control voltage. To analyze the structure,Kramers-Kronig dispersion relations, the effective index method and the Drude model are implemented within a finiteelement software. As a result, for an optical waveguide structure with a 9 mm length and 10 V, it is possible to obtain aphase shift by Df ¼ p that allows, at the output of the MZI, total interference that is required to modulate an opticalcommunication link.
