论文摘要
这项工作证明了电信波长在电信波长处的功能，该功能基于光子集成的SI $ _3 $ n $ _4 $ _4 $微孔子，并单层整合了压电频率调整。以前，仅使用热对照证明了由微孔子产生的光子对的频率调整，但是这些光子对具有有限的致动带宽，并且与低温环境不兼容。在这里，显示了带有单一集成的氮化铝层的Si $ _3 $ n $ _4 $ _4 $ _4 $ _4 $ _4 $ _4 $ n $ _4 $的光子对生成能力。证明了微孔子对外部激光器的快速锁定锁定，结果锁定的带宽数量级比先前使用热锁定的数量级大。这些能力将在未来的方案中具有直接应用，这些方案将与基于量子记忆相接口。被困的离子或稀土离子方案。
This work demonstrates the capabilities of an entangled photon-pair source at telecom wavelengths, based on a photonic integrated Si$_3$N$_4$ microresonator with monolithically integrated piezoelectric frequency tuning. Previously, frequency tuning of photon-pairs generated by microresonators has only been demonstrated using thermal control, however these have limited actuation bandwidth, and are not compatible with cryogenic environments. Here, the frequency-tunable photon-pair generation capabilities of a Si$_3$N$_4$ microresonator with a monolithically integrated aluminium nitride layer are shown. Fast-frequency locking of the microresonator to an external laser is demonstrated, with a resulting locking bandwidth orders of magnitude larger than reported previously using thermal locking. These abilities will have direct application in future schemes which interface such sources with quantum memories based on e.g. trapped-ion or rare-earth ion schemes.
