Abstract
An optical integrated circuit comprises an optical substrate and an optical waveguide supported by the substrate. A transducer is incorporated into the optical integrated circuit and coupled to the optical substrate. The transducer comprises a region of piezo-electric material and a set of electrodes for applying a voltage to the piezo-electric material for selectively causing the deformation of the piezo-electric material so as to alter the optical path length of the waveguide.
