Abstract :
We present a theoretical study of guided-wave acoustooptic (AO) Bragg cells produced by a single surface acoustic wave (SAW) in PE:LiNbO/sub 3//LiNbO/sub 3/- and ZnO/GaAs/AlGaAs-based structures. A rigorous modeling of the SAW propagation in multilayered structures has been used and the analysis of the AO interaction has been performed by using a generalized multimode formulation of the coupled-mode theory. High-performance configurations, particularly advantageous in wide-band optical communication and signal processing applications are presented.
