Abstract

An electro-optic Mach-Zehnder modulator arrangement includes first and second optical waveguides forming, respectively, first and second arms of the Mach-Zehnder modulator. An electrode arrangement includes a first waveguide electrode output port coupled to the first waveguide electrodes a second waveguide electrode arranged on top of a capacitive segment of the first and the second optical waveguides, respectively, such that a voltage can be applied across the capacitive segments of the first and second optical waveguide. At least one driver unit supplies a voltage to the electrode arrangement. The driver unit includes first and second output ports coupled, respectively, to the first and second waveguide electrodes. The driver unit supplies first and second varying signals to the first and second waveguide electrodes via the first and second output ports, respectively. A non-grounded conductive region connects the capacitive segments of the first and second optical waveguides to each other.
