Backward collinear acoustooptic interactions in bulk materials.
Theoretical studies of backward collinear acoustooptic interactions (BCAOI) in both isotropic and anisotropic materials are presented. Such interactions have practical interest as a result of recent progress on very high frequency piezoelectric transducers. BCAOI configurations which involve bulk acoustic waves in fused silica, germanium, and several uniaxial single crystals are analyzed. We discuss propagation loss at high frequency in these materials.
