基于固态发射器（如量子点、分子或金刚石缺陷中心）的单光子源是集成量子技术的关键组件之一。在这里，我们将展示用于集成单光子发射器的不同策略。除此之外，我们引入了一种混合方法，利用金刚石缺陷中心的光子发射和激光写入的光子结构。波导、微谐振器和光学天线可以相对于单个发射器来制造和定向。在我们具体解决通过光学天线有效单光子收集的问题之前，我们先描述我们的一般方法。我们讨论了该方法的局限性、其可扩展性的潜力以及其向光学传感应用的扩展。
Single-photon sources based on solid-state emitters, like quantum dots, molecules or defect centers in diamond, are one of the key components for an integrated quantum technology. Here, we will show different strategies used in order to integrate single-photon emitters. Among others, we introduce an hybrid approach using photon emission from defect centers in diamond and laser-written photonic structures. Waveguides, microresonators, and optical antennas can be fabricated and oriented with respect to the single emitters. We describe our general approach before we specifically address the problem of efficient single-photon collection through optical antennas. We discuss the limitations of the method, its potential for scalability as well as its extension towards optical sensing applications.
