MACH-ZEHNDER MODULATOR ARRANGEMENT AND METHOD FOR OPERATING A MACH-ZEHNDER MODULATOR ARRANGEMENT

摘要

A Mach-Zehnder modulator arrangement includes at least one electro-optic Mach-Zehnder modulator having a first optical waveguide forming a first modulator arm and a second optical waveguide forming a second modulator arm. A travelling wave electrode arrangement includes first waveguide electrodes for applying a voltage across the first optical waveguide and second waveguide electrodes for applying a voltage across the second optical waveguide. The first waveguide electrodes are capacitively coupled to the second waveguide electrodes. A driver unit supplies an alternating voltage to the travelling wave electrode arrangement. The driver unit includes a first output port coupled to the first waveguide electrodes and a second output port coupled to the second waveguide electrodes. The driver unit supplies a first varying signal to the first waveguide electrodes via the first output port and a second varying signal to the second waveguide electrodes via the second output port.
