  • Electro-optic mach-zehnder modulator and method for fabricating an electro-optic mach-zehnder modulator
    Patent number: 10247998
    Abstract: An electro-optic Mach-Zehnder modulator includes a first optical waveguide forming a first arm of the Mach-Zehnder modulator, and a second optical waveguide forming a second arm thereof. The first or second optical waveguide includes capacitive segments that are spaced apart from one another, each forming an electrical capacitor. A travelling wave electrode arrangement applies a voltage across the first or second optical waveguide. The travelling wave electrode arrangement includes waveguide electrodes arranged on the capacitive segments , an electrical line extending along a part of the first or second optical waveguide, the electrical line being arranged a distance from the waveguide electrodes, and connecting arrangements, each being assigned to one of the waveguide electrodes.
