为了获得由具有低驱动电压和高衍射效率的纵向泄漏表面声波（LLSAW）驱动的声光调制器（AOM），质子交换平面光波导型AOM，其结构由X切割36° Y传播LiNbO 3（LN）薄板与AT切割45° X传播石英或c平面蓝宝石（Al 2 O3）结合组成制备衬底并评价其衍射特性。在波长为0.633 μm的0阶横电（TE 0）模光导波中，LN/石英的最大衍射效率为91%，驱动电压为5.1VRMS; LN/Al 2 O3的最大衍射效率为60%，驱动电压为11 VRMS。键合结构上的LLSAW的衍射特性比单个LN衬底上的LLSAW的衍射特性得到了改善。
To obtain an acousto-optic modulator (AOM) driven by a longitudinal leaky surface acoustic wave (LLSAW) with a low driving voltage and a high diffraction efficiency, proton-exchanged planar optical waveguide-type AOMs with structures consisting of an X-cut 36°Y-propagating LiNbO3 (LN) thin-plate bonded to a AT-cut 45°X-propagating quartz or c-plane sapphire (Al2O3) substrate were fabricated and their diffraction properties evaluated. The maximum diffraction efficiency in the zeroth transverse electric (TE0) mode optical guided wave with an optical wavelength of 0.633 μm and the driving voltage required by the LLSAWs of the AOMs were 91% and 5.1 VRMS for LN/quartz and 60% and 11 VRMS for LN/Al2O3, respectively. The diffraction properties of the LLSAWs on the bonded structures were improved compared with those on a single LN substrate.
