我们介绍了混合光子-等离子体纳米谐振器的设计和数值表征，该谐振器由 2D 光子晶体 (PhC) 腔、金领结纳米天线 (BNA) 和二氧化硅 (SiO2) 间隔物组成。该设备旨在作为多组件平台的构建模块，能够同时运行多个单分子实验，例如光学捕获和样品询问。调整间隔层的厚度和结构，以最大化 BNA 间隙中外部可访问热点的能量。该器件对于光子集成的适用性通过光子晶体波导的激发来证明。由光学协会根据知识共享署名 4.0 许可条款发布。
We present the design and numerical characterization of a hybrid photonic-plasmonic nanoresonator comprised of a 2D photonic crystal (PhC) cavity, a gold bowtie nanoantenna (BNA) and a silicon dioxide, SiO2, spacer. This device is designed to serve as the building block of a multicomponent platform capable of running multiple single-molecule experiments such as optical trapping and sample interrogation simultaneously. The thickness and structure of the spacer layer are adjusted to maximize the energy in the externally accessible hot-spot in the BNA gap. Suitability of the device for photonic integration is demonstrated by exciting it through a PhC waveguide.
