Abstract
An arrangement has at least one, and preferably two, optical waveguides integrated on a substrate of electro-optical material, has at least one first electrode for each of the waveguides being applied on the substrate and separated from the waveguide and substrate by an insulating layer and has at least one second electrode for each of the waveguides. The second electrodes are connected to a constant voltage source, while the first electrodes are connected to a modulating voltage source. The constant voltage source applied to the secondary electrodes and the position of these electrodes relative to the waveguides determines an operating point for modulating light in the waveguides.
