光-物质混合态，称为极化激元，是光和物质之间强耦合的结果。极化激元的形成产生了一种新的方法来调整分子系统的能量，从而使物理和化学性质的修改，而不需要化学合成。到目前为止，只有证明的原则研究已经证明，并增加早期成就的相关性，弥合量子电动力学长度尺度和化学合成长度尺度之间的差距是必要的。在目前的研究中，我们表明，光-物质相互作用的耦合强度是独立的法布里-珀罗腔的厚度，和能量耗散率福尔斯下降，增加腔的厚度。使用不同厚度的平面微腔，我们已经表明，腔的大小可以放大，而不降低光与物质之间的强相互作用的强度。这可以达到流动化学中常用的长度尺度，从而为一种新的光流体方法铺平道路，这可能有助于克服有机化学中的挑战。
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-Perot 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.
