Abstract
In this work the modeling of multifrequency acoustooptic interaction in guiding structure is presented. This model, based on a generalized coupled mode theory, allows us to evaluate the Bragg diffraction efficiency when a multifrequency signal is applied to the interdigited transducer. The dependence of diffraction efficiency of the output orders and of the intermodulation factors among the same orders on both the applied voltage amplitudes and transducer driving radiofrequencies has been extensively investigated. Planar waveguide structures on lithium niobate have been considered under monomodal propagation condition.
