The feasibility of many proposals in nanoquantum-optics depends on the efficient coupling of photons to individual quantum emitters, the possibility to control this interaction on demand, and the scalability of the experimental platform. To address these issues, we report on chip-based systems made of one-dimensional subwavelength dielectric waveguides (nanoguides) and polycyclic aromatic hydrocarbon molecules. We discuss the design and fabrication requirements, present data on extinction spectroscopy of single molecules coupled to a nanoguide mode, and show how an external optical beam can switch the propagation of light via a nonlinear optical process. The presented architecture paves the way for the investigation of many-body phenomena and polaritonic states and can be readily extended to more complex geometries for the realization of quantum integrated photonic circuits.
许多纳米量子光学方案的可行性取决于光子与单个量子发射器的有效耦合、按需控制这种相互作用的可能性，以及实验平台的可扩展性。为了解决这些问题，我们报告了基于芯片的一维亚波长介电波导（纳米波导）和多环芳烃分子的系统。我们讨论了设计和制造要求，介绍了与纳米波导模式耦合的单个分子的消光谱数据，并展示了外部光束如何通过非线性光学过程来切换光的传播。所提出的架构为研究多体现象和极化激元态铺平了道路，并且可以很容易地扩展到更复杂的几何形状，以实现量子集成光子电路。
