Acousto-optic (AO) devices are known for their high parallel processing capabilities and efficient transduction; essential for real-time processing systems. As a vital AO medium; chalcogenide glasses exhibit high AO figures of merit (M2); yet high M2 is often coupled with high acoustic attenuation (α). Thus; to obtain the trade-off between M2 and α; a series of xGeSe2−(100−x)Sb2Se3 (40 ≤ x ≤ 85) is investigated for their AO properties. When GeSe2 content reaches 50%; a stable network of [GeSe4] and [Se2Sb–Se–SbSe2] units forms; minimizing energy loss and α while maintaining a high M2. Compared with conventional AO materials; this composition achieves an exceptional equilibrium between high M2 and reduced α; offering a distinct advantage in optimizing performance. This unique composition balance provides valuable insights for developing advanced chalcogenide glasses in AO applications. © 2024 The American Ceramic Society;
