Paper Abstract

A variety of hybrid surface acoustic waves (SAW)-based integrated acousto-optic (AO) Bragg cell 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 previously in common LiNbO3 substrate up to 1.0 X 3.7 cm2 in maximum size. The prospects for realization of their counterparts in monolithic integrated format in a common substrate of InGaAsP material system are significantly enhanced recently. In the meantime, the magnetooptic (MO) Bragg interactions between guided optical waves and magnetostatic waves in yttrium iron garnet- gadolinium gallium garnet substrates have resulted in miniaturized MO Bragg cell modulators in analogy with the guided-wave AO Bragg cell modulators. 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. Such MO modulators have been utilized to demonstrate a number of novel applications. In this paper, a review of some of the most recent advances in integrated AO and MO device modules and applications together with some unpublished new results are presented.
