Abstract

Bragg diffraction of guided-optical waves from the surface acoustic waves (SAW) and the resulting acoustooptic (AO) Bragg devices in LiNbO₃-based planar optical waveguides have been extensively studied.¹ In fact, utilization of the resulting wideband Bragg cells for development and realization of integrated-optic rf signal processors has become an international effort. Spherical waveguide AO Bragg cells in LiNbO₃ explored most recently² have also demonstrated a number of potential applications in rf signal processing and optical frequency shifting. Such spherical waveguide AO device modules have been shown to possess a number of unique features that enable them to be more readily interfaced with the single-mode optical fibers.
