Hybrid light‐matter states, known as polaritons, are the result of strong coupling between light and matter. The formation of polaritons yields a new method to tune the energetics of molecular systems, thus enabling the modification of physical and chemical properties without the need for chemical synthesis. To date, only proof‐of‐principle studies have been demonstrated, and, to increase the relevance of earlier achievements, bridging the gap between quantum electrodynamic length scales and chemical synthesis length scales is necessary. In the present study, we show that the coupling strength of the light‐matter interaction is independent of the thickness of the Fabry‐Pérot cavity used, and that the energy dissipation rate falls with increasing cavity thickness. Using planar microcavities of different thicknesses, we have shown that the size of the cavities can be upscaled without reducing the strength of the strong interaction between light and matter. This can be done up to a length scale commonly used in flow chemistry, thus paving the way for a new optofluidic method that may help to overcome challenges in organic chemistry.

耦合模式在振动强耦合系统中的作用

混合光物质状态，称为极化子，是光与物质之间强耦合的结果。极化子的形成产生了一种新的方法来调节分子系统的能量，从而无需化学合成即可改变物理和化学性质。迄今为止，仅证明了原理验证研究，并且为了增加早期成就的相关性，有必要弥合量子电动力学长度标度与化学合成长度标度之间的差距。在本研究中，我们表明光-质相互作用的耦合强度与所使用的Fabry-Pérot腔的厚度无关，并且能量耗散率随腔厚度的增加而降低。使用不同厚度的平面微腔，我们已经表明，在不降低光与物质之间强相互作用的强度的情况下，可以扩大空腔的尺寸。这可以达到流化学中通常使用的长度尺度，从而为新的光流体方法铺平了道路，该方法可以帮助克服有机化学中的挑战。
