将二维半导体单层集成到光学微腔中是具有挑战性的，因为很少有可用的方法在单层上涂覆介电材料而不损坏它们。已经开发了一些策略，但它们要么依赖于复杂的实验设置和昂贵的技术，要么限制了可实现的腔品质因数。因此，高质量的法布里-珀罗微腔并没有广泛地应用于关注原子级薄材料中的光-物质耦合的社区。在这里，我们详细介绍了最近开发的技术，微机械组装法布里-珀罗微腔。我们的方法促进了原子级薄材料中激子的强耦合条件，它不依赖于困难或昂贵的技术，它是可重复的，并且它产生的微腔质量因子接近4000。它非常适合在小规模实验室中设计先进复杂的耦合单层腔系统。
Integrating monolayers of two-dimensional semiconductors into optical microcavities is challenging because of the very few available approaches to coat the monolayers with dielectric materials without damaging them. Some strategies have been developed, but they either rely on complicated experimental settings and expensive technologies or limit the achievable cavity quality factors. Thus, high quality Fabry-Perot microcavities are not widely available to the community focusing on light-matter coupling in atomically thin materials. Here, we detail a recently developed technique to micro-mechanically assemble Fabry-Perot microcavities. Our approach promotes strong coupling conditions with excitons in atomically thin materials, it does not rely on difficult or expensive technologies, it is reproducible, and it yields microcavities with quality factors approaching 4000. It is ideally suitable for engineering coupled monolayer-cavity systems of advanced complexity in small-scale laboratories.
