AI 中文摘要
将膜集成到光学谐振器在包括光机械学在内的各种应用中起着关键作用。承载单光子发射器（理想情况下可访问自旋态）的膜在光机械学、自旋机械学和自旋光机械学中开辟了新途径。六方氮化硼是最有前途的二维材料之一，具有优异的光学和机械性能以及承载光学活性（自旋）缺陷的能力。在六方氮化硼膜中确定性地创建光学活性缺陷中心并将其与光机械系统耦合是一项重大挑战。本文探索了一种替代混合方法，以在市售六方氮化硼薄片中的单光子发射器与光纤腔模式之间建立耦合。解决了诸如由不受控制的薄片形貌引起的散射损耗等技术挑战，并在腔镜上确定了六方氮化硼的位置。对于耦合系统，在室温下观察到腔诱导光谱增强高达100倍。通过将六方氮化硼薄片中的单光子发射器置于中间膜配置的高应变氮化硅膜上扩展了工作。同时观察到氮化硅膜的机械振动模式和单光子发射器的腔耦合发射。我们的工作是迈向实现包含单光子发射器的腔光机械平台的第一步，并为探索混合自旋光机械学提供了起点。
英文摘要
The integration of membranes into optical resonators plays a key role in a variety of applications, including optomechanics. Membranes hosting single photon emitters, ideally with access to spin states, open new avenues in optomechanics, spin-mechanics and spin-optomechanics. Hexagonal boron nitride is among the most promising two-dimensional materials, showing excellent optical and mechanical properties combined with the ability to host optically active (spin) defects. The deterministic creation of optically active defect centers in hexagonal boron nitride membranes and their coupling to optomechanical systems is an outstanding challenge. Here, we explore an alternative hybrid approach to establish coupling between a single photon emitter in commercially available hexagonal boron nitride flakes and a fiber cavity mode. We address technical challenges, such as scattering losses arising from uncontrolled flake topography, and establish deterministic hexagonal boron nitride positioning on the cavity mirror. For the coupled system, we observe cavity-induced spectral enhancement by a factor of up to 100 at room temperature. We extend our work by positioning single photon emitters in hexagonal boron nitride flakes on a highly strained silicon nitride membrane in a membrane-in-the-middle configuration. The mechanical vibrational modes of the silicon nitride membrane and cavity-coupled emission from the single photon emitter are simultaneously observed. Our work is a first step towards the realization of a cavity optomechanical platform with an incorporated single photon emitter and provides a starting point to explore hybrid spin-optomechanics.
