We demonstrate the first wavelength-tunable electrically pumped source of nonclassical light that can emit photons with wavelength in resonance with the D transitions of Rb atoms. The device is fabricated by integrating a novel GaAs single-quantum-dot light-emitting diode (LED) onto a piezoelectric actuator. By feeding the emitted photons into a 75 mm long cell containing warm Rb vapor, we observe slow-light with a temporal delay of up to 3.4 ns. In view of the possibility of using Rb atomic vapors as quantum memories, this work makes an important step toward the realization of hybrid-quantum systems for future quantum networks.
我们展示了首个波长可调谐的电泵浦非经典光源，它能够发射与铷原子D跃迁共振的波长的光子。该器件是通过将新型砷化镓单量子点发光二极管（LED）集成到压电致动器上制造而成。通过将发射的光子注入到一个装有温热铷蒸汽的75毫米长的气室中，我们观测到了时间延迟高达3.4纳秒的慢光。鉴于使用铷原子蒸汽作为量子存储器的可能性，这项工作朝着实现用于未来量子网络的混合量子系统迈出了重要一步。
