论文摘要
分子强耦合为物理，化学和材料科学提供了令人兴奋的前景。尽管注意力集中在为分子系统开发现实模型上，但探索了光腔的整个光子模式结构的重要作用。我们表明，分子强耦合的有效性可能主要取决于腔体的技巧。具体而言，我们只看到与具有足够技巧的空腔的分散性下极化相关的发射。通过在多模结构中开发一个空腔光致发光的分析模型，我们阐明了有限的技巧在北极星形成中的作用，并表明降低技巧会降低北极星状态下光和物质的混合程度。我们建议，腔体支持的光子模式的详细性质对于开发分子强耦合的连贯框架与包含逼真的分子模型一样重要。
Molecular strong coupling offers exciting prospects in physics, chemistry and materials science. Whilst attention has been focused on developing realistic models for the molecular systems, the important role played by the entire photonic mode structure of the optical cavities has been less explored. We show that the effectiveness of molecular strong coupling may be critically dependent on cavity finesse. Specifically we only see emission associated with a dispersive lower polariton for cavities with sufficient finesse. By developing an analytical model of cavity photoluminescence in a multimode structure we clarify the role of finite-finesse in polariton formation, and show that lowering the finesse reduces the extent of the mixing of light and matter in polariton states. We suggest that the detailed nature of the photonic modes supported by a cavity will be as important in developing a coherent framework for molecular strong coupling as the inclusion of realistic molecular models.
