量子光源和非线性元件的片上集成构成了可扩展的基于光子的量子信息处理和通信的重要一步。在这项工作中，我们展示了混合技术的潜力，该技术结合了基于有机分子的量子发射器和由脊波导和光栅远场耦合器组成的电介质芯片。特别是，dibenzoterrylene分子在薄的蒽晶体被用作单光子源，表现出长期的光稳定性，易于制造的方法，几乎单一的量子产率，并在低温下的寿命有限的发射。我们这样的单发射器耦合到氮化硅脊形波导，在两个传播方向上的耦合效率高达42 +/- 2%。我们的研究结果为完全集成和可扩展的光子处理平台开辟了一条新的道路。
The on-chip integration of quantum light sources and nonlinear elements constitutes a major step toward scalable photon-based quantum information processing and communication In this work we demonstrate the potential of a hybrid technology that combines organic molecule-based quantum emitters and dielectric chips consisting of ridge waveguides and grating far-field couplers. In particular, dibenzoterrylene molecules in thin anthracene crystals are used as single-photon sources, exhibiting long-term photostability, easy fabrication methods, almost unitary quantum yield, and lifetime-limited emission at cryogenic temperatures. We couple such single emitters to silicon nitride ridge waveguides, showing a coupling efficiency of up to 42 +/- 2% over both propagation directions. Our results open a novel path toward a fully integrated and scalable photon processing platform.
