量子光子学为未来的技术，如安全通信，量子计算，量子模拟和量子计量学带来了巨大的希望。量子光子学面临的一个突出挑战是开发可扩展的微型电路，将单光子源，线性光学元件和探测器集成在芯片上。等离子体纳米电路将在这种发展中发挥重要作用。然而，对于量子等离子体激元电路，在结构中集成稳定、明亮和窄带的单光子源到目前为止还没有报道。在这里，我们提出了一个由自组装GaAs量子点驱动的等离子体激元纳米电路。通过平面介电-等离子体混合波导，量子点有效地激发窄带单等离子体激元，这些单等离子体激元在双线传输线中被引导，直到它们被光学天线转换成单光子。我们的工作证明了完全片上等离子体纳米电路用于量子光学应用的可行性。
Quantum photonics holds great promise for future technologies such as secure communication, quantum computation, quantum simulation, and quantum metrology. An outstanding challenge for quantum photonics is to develop scalable miniature circuits that integrate single-photon sources, linear optical components, and detectors on a chip. Plasmonic nanocircuits will play essential roles in such developments. However, for quantum plasmonic circuits, integration of stable, bright, and narrow-band single photon sources in the structure has so far not been reported. Here we present a plasmonic nanocircuit driven by a self-assembled GaAs quantum dot. Through a planar dielectric-plasmonic hybrid waveguide, the quantum dot efficiently excites narrow-band single plasmons that are guided in a two-wire transmission line until they are converted into single photons by an optical antenna. Our work demonstrates the feasibility of fully on-chip plasmonic nanocircuits for quantum optical applications.
