论文摘要
狭窄线宽度的固态单光子源（SPSS）在许多领先的量子技术中起着重要作用。在迄今为止研究的广泛的SPS中，在有机晶体中宿主的单个荧光分子在低温温度下脱颖而出，具有寿命有限的光学共振。此外，最近的结果表明，在纳米晶环境中托管的单分子仍然观察到光稳定性和狭窄的线宽度，这为它们与光子电路的整合铺平了道路。聚合物提供了一种兼容的矩阵，用于嵌入纳米晶体，并提供一种多功能但低成本的方法，用于在芯片上制造纳米光结构，以引导光线并增强纳米级发射器的耦合。在这里，我们提出了一种基于电子束光刻的确定性纳米结构技术，用于用嵌入式单分子塑造聚合物。我们的方法提供了一种直接的方法，可以在保留其发射特性的同时构建狭窄线宽度发射器的纳米级环境。
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.
