在过去的几年里，在利用片上光子-声子相互作用方面取得了重大进展，导致了新功能的广泛展示。不仅利用非线性波导的光学响应，而且利用声共振，能够实现具有前所未有的性能的微波器件，否则很难在全光处理方案或电子实现。在这里，我们概述了片上受激布里渊散射（SBS），特别强调微波源和微波信号处理方案。我们回顾了不同的材料平台和结构的片上SBS，从硫族化物脊形波导的混合硅/氮化硅结构，高Q光子声子二氧化硅微谐振器，和悬浮硅纳米线。我们表明，SBS研究的范式转变-从长光纤到芯片级器件-现在正朝着完全集成的光子-声子CMOS芯片发展。
The last few years have seen major progress in harnessing on-chip photon-phonon interactions, leading to a wide range of demonstrations of new functionalities. Utilizing not only the optical response of a nonlinear waveguide-but also acoustic resonances-enables the realization of microwave devices with unprecedented performance, otherwise hard to achieve in all-optical processing schemes or electronically. Here, we overview on-chip stimulated Brillouin scattering (SBS) with special emphasis on microwave sources and microwave signal processing schemes. We review the different material platforms and structures for on-chip SBS, ranging from chalcogenide rib waveguides to hybrid silicon/silicon-nitride structures, high-Q photonic-phononic silica microresonators, and suspended silicon nanowires. We show that the paradigm shift in SBS research-from long length of fibers to chip-scale devices-is now moving toward fully integrated photonic-phononic CMOS chips.
