Abstract: An optical component, such as, for example, a Mach-Zehnder modulator, in which the ground electrodes are formed directly on a surface of a substrate, that is, without the intermediary of or presence of conventional buffer dielectric layers. Forming the optical component without a dielectric layer between the ground electrodes and the substrate allows for a reduction in the drive voltage in the operation of the modulator.
