标题： Enhancing Four-Wave-Mixing Processes by Nanowire Arrays Coupled to a Gold Film

摘要： 我们考虑金纳米线阵列与金膜强耦合中的四波混频过程。 通过全波仿真，我们对与薄膜几何结构相关的四波混频效率进行了定量比较，包括有和没有纳米线阵列的情况。 当存在纳米线阵列时，薄膜的扩展表面等离子体以及纳米线的局域表面等离子体共振都会对局部场增强做出贡献，从而在广泛的激发角度范围内，使整体四波混频效率提高了多达四个数量级。 与薄膜耦合的纳米线阵列易于进行纳米制造，并可能作为超紧凑组件用于集成光子和量子光学系统。 显示英文摘要

摘要： We consider the process of four-wave mixing in an array of gold nanowires strongly coupled to a gold film. Using full-wave simulations, we perform a quantitative comparison of the four-wave mixing efficiency associated with the thin film geometry with and without the nanowire arrays. When the nanowire array is present, both the delocalized surface plasmon of the film as well as the localized surface plasmon resonances of the nanowires contribute to the local field enhancement, yielding an overall FWM efficiency enhancement of up to four orders-of-magnitude over a wide range of excitation angles. The film-coupled nanowire array is easily amenable to nanofabrication, and could find application as an ultra-compact component for integrated photonic and quantum optic systems.
