Color centers integrated with nanophotonic devices have emerged as a compelling platform for quantum science and technology. Here, we integrate tin-vacancy centers in a diamond waveguide and investigate the interaction with light at the single-photon level in both reflection and transmission. We observe single-emitter-induced extinction of the transmitted light up to 25% and measure the nonlinear effect on the photon statistics. Furthermore, we demonstrate fully tunable interference between the reflected single-photon field and laser light backscattered at the fiber end and show the corresponding controlled change between bunched and antibunched photon statistics in the reflected field.
与纳米光子器件集成的色心已成为量子科学与技术中一个引人注目的平台。在此，我们将锡空位色心集成到金刚石波导中，并研究其在反射和透射中与单光子水平光的相互作用。我们观察到单发射体导致透射光的消光高达25%，并测量了对光子统计的非线性效应。此外，我们展示了反射单光子场与光纤末端背向散射的激光之间完全可调的干涉，并展示了反射场中聚束和反聚束光子统计之间相应的可控变化。
