Abstract: A Mach-Zehnder optical modulator is provide and has a travelling wave electrode extending over two optical waveguide branches and modulating the relative phase of the optical beam components propagating in those branches. The travelling wave electrode has transmission line conductors and pairs of waveguide electrodes, the waveguide electrodes of each pair being coupled to one of the optical waveguide branches, respectively. The travelling wave electrode further includes active devices having a high impedance input electrically connected to one of the transmission line conductors and a low impedance output electrically connected to one of the waveguide electrodes. Each active device transfers the electrical modulation signal from the associated transmission line conductor onto the associated waveguide electrode according to a voltage transfer function.
