近年来，引导光波和表面声波 (SAW) 之间的声光 (AO) 布拉格相互作用以及由此产生的 AO 布拉格单元调制器在集成 AO 技术中不断发展。各种混合多通道集成AO器件模块，包括功率和干涉式射频频谱分析仪、空间开关、可调谐滤波器、移频器和调制器、模拟代数处理器、可编程相关器和其他多通道器件模块，已在最大尺寸达1.0/spl times/3.7 cm/sup 2/的常见LiNbO/sub 3/基板上实现。最近，在 InGaAsP 材料系统的通用衬底中以单片集成形式实现其对应物的前景也显着增强。这些 AO 器件模块显示出高度的模块化，并建议在光学信息处理和通信中应用。与此同时，钇铁石榴石-钆镓石榴石（YIG-GGG）波导中导光波和静磁波（MSW）之间的磁光（MO）布拉格相互作用产生了类似于导波AO布拉格单元调制器的小型化MO布拉格单元调制器。最近，此类MO布拉格单元调制器的性能得到了显着改善，并且调制器已与离子铣削波导透镜集成以实现混合集成MO器件模块，并已用于演示许多新颖的应用。本文对其中一些集成 AO 和 MO 设备模块和应用进行了回顾，并介绍了一些未发表的新成果。
Acoustooptic (AO) Bragg interactions between guided optical waves and surface acoustic waves (SAW's) and the resulting AO Bragg cell modulators have evolved in integrated AO technology in recent years. A variety of hybrid multichannel integrated AO device modules including power and interferometric RF spectrum analyzers, space switches, tunable filters, frequency shifters and modulators, analog algebraic processors, programmable correlators and other multichannel device modules have been realized in common LiNbO/sub 3/ substrate up to 1.0/spl times/3.7 cm/sup 2/ in maximum size. The prospects for realization of their counterparts in monolithic integrated format in a common substrate of InGaAsP material system are also significantly enhanced recently. These AO device modules have shown a high degree of modularity and suggested applications in optical information processing and communications. In the meantime, the magnetooptic (MO) Bragg interactions between guided optical waves and magnetostatic waves (MSWs) in yttrium iron garnet-gadolinium gallium garnet (YIG-GGG) waveguides have resulted in miniaturized MO Bragg cell modulators in analogy with the guided-wave AO Bragg cell modulators. Most recently the performance of such MO Bragg cell modulators has been significantly improved and the modulators have been integrated with ion-milled waveguide lenses to realize hybrid integrated MO device modules, and have been utilized to demonstrate a number of novel applications. In this paper, a review of some of these integrated AO and MO device modules and applications together with some unpublished new results are presented.
