Coherent and perfect absorption with organic molecules: an exploration of strong and ultra-strong light-matter coupling

光与物质之间的强耦合意味着光子可以在光子逃逸或物质激发衰变之前被吸收和重新发射多次。超强耦合意味着物质和光之间的转换开始接近空腔光子的裸频率。在这种情况下，不再适合单独考虑物质和光，而是考虑组合系统，材料性质也不能再孤立地计算。虽然这些想法已经在太赫兹或千兆赫频率辐射的背景下讨论了一段时间，但最近已经可以在光学频率下使用光学微腔中的有机分子[1,2]。该项目的目的是探索这些系统中的各种强耦合和超强耦合现象，包括相干完全吸收[3,4]（其中使用镜面透射和非辐射损耗之间的阻抗匹配来确保向物质-光系统的最大能量传递）。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侧带如何影响强和超强耦合现象。S. ksamna - cohen， S. a.

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.
