论文摘要
与腔体光学机械类似，增强具有窄带光学谐振器的拉曼过程的特定侧带将允许参数放大，光和分子振动的纠缠以及减少转导噪声。我们报告了波导 - 可调式侧带分辨的表面增强拉曼散射（SERS）的演示。我们意识到了一个由1D光子晶体腔组成的混合等离子体 - 光子谐振器，该光子晶体腔装饰有低于20 nm的缝隙二聚体纳米annoantenna。近红外的混合共振提供了1000的设计器Q因子，$ q/v =（λ^3/10^6）^{ - 1} $，s信号强度与最先进的纯等离子系统中的水平相当。我们证明有机分子的SERS增强中的Fano-Lineshapes，并定量地将泵的增强和光储层贡献分开。
In analogy to cavity optomechanics, enhancing specific sidebands of a Raman process with narrowband optical resonators would allow for parametric amplification, entanglement of light and molecular vibrations, and reduced transduction noise. We report on the demonstration of waveguide-addressable sideband-resolved surface-enhanced Raman scattering (SERS). We realized a hybrid plasmonic-photonic resonator consisting of a 1D photonic crystal cavity decorated with a sub-20 nm gap dimer nanoantenna. Hybrid resonances in the near-IR provide designer Q-factors of 1000, and $Q/V=(λ^3/10^6)^{-1}$, with SERS signal strength on par with levels found in state-of-the-art purely plasmonic systems. We evidence Fano-lineshapes in the SERS enhancement of organic molecules, and quantitatively separate out the pump enhancement and optical reservoir contributions.
