Abstract
An integrated optical structure creating directional coupling between two waveguides in which an index disturbance accompanying the guided photons is caused to act on two closely-spaced waveguides, this disturbance being produced by a progressive elastic wave with sloping wavefronts emitted by an electromechanical transducer.
