An acousto-optically coupled asymmetric waveguide pair and method of operation is disclosed. A pair of dielectric optic waveguides are defined in close proximity. Each waveguide is characterized by a propagation constant at which it can support propagation of a signal. An acoustic surface wave is effective to vary the propagation constant of the waveguides such that the signal is switched from one waveguide to the other.
