Photonic and plasmonic systems have been intensively studied as an effective means to modify and enhance the electromagnetic field. In recent years hybrid plasmonic-photonic systems have been investigated as a promising solution for enhancing light-matter interaction. In the present work we present a hybrid structure obtained by growing a plasmonic 2D nanograting on top of a porous silicon distributed Bragg reflector. Particular attention has been devoted to the morphological characterization of these systems. Electron microscopy images allowed us to determine the geometrical parameters of the structure. The matching of the optical response of both components has been studied. Results indicate an interaction between the plasmonic and the photonic parts of the system, which results in a localization of the electric field profile.
光子和等离子体系统作为一种修改和增强电磁场的有效手段已得到深入研究。近年来，混合等离子体-光子系统作为增强光与物质相互作用的一种有前景的解决方案受到了研究。在本工作中，我们展示了一种通过在多孔硅分布布拉格反射器顶部生长等离子体二维纳米光栅而获得的混合结构。我们对这些系统的形态表征给予了特别关注。电子显微镜图像使我们能够确定结构的几何参数。我们研究了两个组件的光学响应的匹配情况。结果表明系统的等离子体部分和光子部分之间存在相互作用，这导致了电场分布的局域化。
