窄线宽固态单光子源在许多前沿量子技术中发挥着重要作用。在迄今为止研究的各种SPS中，有机晶体中的单个荧光分子在低温下具有寿命有限的光学共振，作为明亮的光稳定SPS脱颖而出。此外，最近的结果表明，光稳定性和窄线宽仍然可以从纳米晶环境中的单分子中观察到，这为它们与光子电路的集成铺平了道路。聚合物为嵌入纳米晶体提供了一种兼容的基质，并为在芯片上制造纳米光子结构提供了一种通用而低成本的方法，该结构可以引导光并增强与纳米级发射器的耦合。在这里，我们提出了一个确定性的纳米结构技术的基础上，电子束光刻成型聚合物与嵌入的单分子。我们的方法提供了一种直接的手段，结构化的纳米级环境的窄线宽发射器，同时保持其发射特性。
Solid-state single photon sources (SPSs) with narrow line width play an important role in many leading quantum technologies. Within the wide range of SPSs studied to date, single fluorescent molecules hosted in organic crystals stand out as bright, photostable SPSs with a lifetime-limited optical resonance at cryogenic temperatures. Furthermore, recent results have demonstrated that photostability and narrow line widths are still observed from single molecules hosted in a nanocrystalline environment, which paves the way for their integration with photonic circuitry. Polymers offer a compatible matrix for embedding nanocrystals and provide a versatile yet low-cost approach for making nanophotonic structures on chip that guide light and enhance coupling to nanoscale emitters. Here, we present a deterministic nanostructuring technique based on electron-beam lithography for shaping polymers with embedded single molecules. Our approach provides a direct means of structuring the nanoscale environment of narrow line width emitters while preserving their emission properties.
