Abstract
The invention relates to an electro-optic modulator, in particular a Mach-Zehnder modulator or an electro-absorption modulator, comprising: - at least one optical waveguide (11, 12); - a travelling-wave electrode arrangement (2, 2000) comprising at least one waveguide electrode (221, 222, 2100) for applying a voltage across the optical waveguide (11, 12) and at least one electrical line (223, 224, 2300, 2400) and/or another waveguide electrode (221, 222), wherein at least one voltage source (41, 4100) is to be connected to the waveguide electrode (221, 222, 2100) and the electrical line (223, 224, 2300, 2400) or the other waveguide electrode (221, 222) in such a way that the potential of the waveguide electrode (221, 222, 2100) is different from the potential of the electrical line (223, 224, 2300, 2400) and the other waveguide electrode (221, 222), respectively; and - at least one electrically conductive connecting element (3, 3a, 3b) generating a short-circuit between the waveguide electrode (221, 222, 2100) and the electrical line (223, 224, 2300, 2400) and/or between the waveguide electrode (221, 222, 2100) and the other waveguide electrode (221, 222). The invention also relates to a method for fabricating an electro-optic modulator.
