ABSTRACT:
An optical phase shifter comprises an optical waveguide of electro-optic material and an electrode structure associated with the waveguide for imposing an electrical field on the waveguide. The electrode structure comprises at least two groups of electrodes, each group having at least first and second electrodes between which the waveguide passes. The first electrode of one group and the second electrode of the other group are on opposite respective sides of the waveguide and are connected to respective input terminals for receiving an electrical signal. The second electrode of the one group is connected to the first electrode of the other group.
