Strong coupling between light and matter means that photons can be absorbed and re-emitted many times before photons escape, or material excitations decay. Ultrastrong coupling means that the conversion between matter and light starts to approach the bare frequency of the cavity photons. In this regime, it is no longer appropriate to think of matter and light separately, but of the combined system, and the material properties can no longer be calculated in isolation. While such ideas have been discussed for some time in the context of THz or GHz frequency radiation, it has recently become accessible at optical frequencies using organic molecules in optical microcavities [1,2]. The aim of this project will be to explore a variety of strong and ultra-strong coupling phenomena in these systems, including coherent perfect absorption [3,4] (where impedance matching between mirror transmission and non-radiative losses is used to ensure maximum energy transfer to the matter-light system). In particular, building on recent work[5], we will explore how the vibrational sidebands present in molecular systems affect phenomena of strong and ultra-strong coupling. [1] S. Kéna-Cohen, S. a.

光和物质之间的强耦合意味着光子在光子逸出之前可以被吸收和重新发射多次，或者材料激发衰减，超强耦合意味着物质和光之间的转换开始接近腔光子的裸频率。在这种情况下，单独考虑物质和光不再合适，而应该考虑组合系统，并且材料特性不再能够单独计算，尽管这种想法已经在太赫兹或千兆赫频率的背景下讨论了一段时间。辐射，最近可以在光学微腔中使用有机分子的光学频率[1,2]该项目的目的是探索这些系统中的各种强和超强耦合现象，包括相干完美吸收[3,4]（其中阻抗匹配）。特别是，在最近的工作[5]的基础上，我们将探索分子系统中存在的振动边带如何影响强和光现象。超强耦合[1] S.
