Abstract
An electro-optical modulator is provided. The electro-optical modulator comprises at least one optical waveguide, an electrode arrangement for applying a voltage across the optical waveguide. The electrode arrangement comprises a first and a second electrical line and at least two terminating resistors terminating the first and the second electrical line. The electrode arrangement comprises at least one capacitive structure that capacitively couples, but galvanically separates the two terminating resistors. The capacitive structure comprises at least two electrically conductive layers physically arranged at a position between the first and the second electrical line, wherein the at least two layers are separated by at least one dielectric layer.
