Title: Brillouin Optomechanics in Photonic Integrated Circuits

Abstract: Stimulated Brillouin scattering (SBS) is a coherent optomechanical interaction between light and gigahertz acoustic waves that can unlock promising technologies including narrow-linewidth lasers, microwave photonic signal processing, and on-chip nonreciprocal light propagation. Recently, SBS has extensively been studied in integrated waveguides. However, many implementations rely on complicated fabrication schemes, using suspended waveguides, or non-standard materials. The absence of SBS in standard and mature fabrication platforms prevents large-scale circuit integration and severely limits the potential of this technology. In this talk, I will focus on our recent results on enhancement of SBS in scalable integration platform including silicon nitride [1-3] and thin-film lithium niobate and I will discuss the potential applications of this technology.
