Development of acoustic and optoacoustic on-chip technologies calls for new solutions to guiding, storing and interfacing acoustic and optical waves in integrated silicon-on-insulator (SOI) systems. One of the biggest challenges in this field is to suppress the radiative dissipation of the propagating acoustic waves, while co-localizing the optical and acoustic fields in the same region of an integrated waveguide. Here we address this problem by introducing Anti-Resonant Reflecting Acoustic Waveguides (ARRAWs) --- mechanical analogues of the Anti-Resonant Reflecting Optical Waveguides (ARROWs). We discuss the principles of anti-resonant guidance and establish guidelines for designing efficient ARRAWs. Finally, we demonstrate examples of the simplest silicon/silica ARRAW platforms that can simultaneously serve as near-IR optical waveguides, and support strong backward Brillouin scattering.

ARRAW:抗共振反射声波导管

声学和光声片上技术的发展需要新的解决方案来引导、存储和连接集成绝缘体上硅 (SOI) 系统中的声波和光波。该领域的最大挑战之一是抑制传播声波的辐射耗散,同时将光场和声场共定位在集成波导的同一区域。在这里,我们通过引入抗谐振反射声波波导 (ARRAW) 来解决这个问题——抗谐振反射光波导 (ARROW) 的机械类似物。我们讨论了反共振引导的原则,并为设计高效的 ARRAW 建立了指导方针。最后,我们展示了可以同时用作近红外光波导的最简单的硅/二氧化硅 ARRAW 平台的示例,
