单晶金刚石薄膜具有光活性发射体，是集成量子纳米光子学中极具吸引力的元件。在这项工作中，我们展示了自底向上合成含有锗空位（GeV）色中心的单晶金刚石膜。在锗源存在的情况下，我们采用一种升起技术来生成膜，并进行化学气相沉积，以实现原位掺杂。最后，我们证明了这些膜适用于微盘腔等光子谐振器的工程设计，其质量因子接近1500。设计包含新兴色心的单晶金刚石膜是在芯片上实现金刚石集成量子纳米光子电路的一条有前途的途径。
Single crystal diamond membranes that host optically active emitters are highly attractive components for integrated quantum nanophotonics. In this work we demonstrate bottom-up synthesis of single crystal diamond membranes containing germanium vacancy (GeV) color centers. We employ a lift-off technique to generate the membranes and perform chemical vapor deposition in the presence of a germanium source to realize the in situ doping. Finally, we show that these membranes are suitable for engineering of photonic resonators such as microdisk cavities with quality factors of similar to 1500. The robust and scalable approach to engineer single crystal diamond membranes containing emerging color centers is a promising pathway for the realization of diamond integrated quantum nanophotonic circuits on a chip.
