Abstract

The invention relates to a Mach-Zehnder modulator arrangement, comprising - at least one electro-optic Mach-Zehnder modulator (1) comprising a first optical waveguide (11) forming a first modulator arm and a second optical waveguide (12) forming a second modulator arm; - a travelling wave electrode arrangement (2) comprising a plurality of first waveguide electrodes (21) for applying a voltage across the first optical waveguide (11) and a plurality of second waveguide electrodes (22) for applying a voltage across the second optical waveguide (12), wherein the first waveguide electrodes (21) are capacitively coupled to the second waveguide electrodes (22); and - a driver unit (41) for supplying an alternating voltage to the travelling wave electrode arrangement (2), wherein - the driver unit (41) comprises a first output port (441) coupled to the first waveguide electrodes (21) and a second output port (442) coupled to the second waveguide electrodes (22), wherein the driver unit (41) is configured to supply a first varying signal (S+) to the first waveguide electrodes (21) via the first output port (441) and to supply a second varying signal (S-) to the second waveguide electrodes (22) via the second output port (442). The invention further relates to a method for operating a Mach-Zehnder modulator arrangement.
