Abstract
A Mach-Zehnder optical modulator with a travelling wave electrode has a signal transmission line conductor (S) carrying an input electrical signal, and two ground transmission line conductors (Gand G) providing a return path for the electrical signal. The signal transmission line conductor is positioned between the first and second ground lines, and the first and second optical waveguide branches are positioned between the signal transmission line conductor and the first ground line. The modulator therefore has a GSG structure providing an asymmetrically-loaded configuration.
