Abstract
An electro-optic device, such as a Mach-Zehnder interferometer or a directional coupler, has a power dissipating electrode structure and a ground plane electrode, and is switchable between first and second distinct states by the application of respective first and second potentials to the power dissipating electrode. Thermally induced instabilities are minimized by biasing the ground plane electrode such that the first and second potentials are of substantially equal magnitude but of opposite sign. The power dissipating electrode may be a travelling-wave electrode connected to a 50 ohm transmission line.
