摘要

光学腔中分子材料的室温腔量子电动力学为控制电子、核和光子自由度在物理、化学和材料科学中的应用提供了令人兴奋的前景。然而,实现与分子系综的强耦合通常需要高分子密度和大量的电磁场约束。这些条件通常涉及显著程度的分子无序和高度结构化的光子密度态。目前还不清楚这些额外的复杂性在多大程度上改变了原子和无机半导体的强耦合的通常物理图景。利用实际多模光学谐振器中分子系综的微观量子描述,我们证明了线性光谱中真空拉比分裂的出现是光与物质相干混合的必要但不充分的度量。在低精细度的多模情况下,我们发现分子偶极子可以与非谐振腔模式相关的光子耗散通道部分杂化。这些真空诱导的耗散过程最终限制了系统所能维持的光-物质相干性的程度。这篇文章是主题“光的量子理论”的一部分。

Multiple interacting photonic modes in strongly coupled organic microcavities.

Room-temperature cavity quantum electrodynamics with molecular materials in optical cavities offers exciting prospects for controlling electronic, nuclear and photonic degrees of freedom for applications in physics, chemistry and materials science. However, achieving strong coupling with molecular ensembles typically requires high molecular densities and substantial electromagnetic-field confinement. These conditions usually involve a significant degree of molecular disorder and a highly structured photonic density of states. It remains unclear to what extent these additional complexities modify the usual physical picture of strong coupling developed for atoms and inorganic semiconductors. Using a microscopic quantum description of molecular ensembles in realistic multimode optical resonators, we show that the emergence of vacuum Rabi splitting in linear spectroscopy is a necessary but not sufficient metric of coherent admixing between light and matter. In low-finesse multi-mode situations, we find that molecular dipoles can be partially hybridized with photonic dissipation channels associated with off-resonant cavity modes. These vacuum-induced dissipative processes ultimately limit the extent of light-matter coherence that the system can sustain.This article is part of the theme issue 'The quantum theory of light'.
