Plasmonic-Organic Microcavity Lasers

在这个项目中，我们希望实现有机纳米粒子激光器的新概念。目标是了解结合等离子体表面晶格共振和分布布拉格反射器的复合有机纳米粒子腔的激光行为。在前期工作中，我们已经证明了在微腔中嵌入金属纳米粒子和有机发射器可以实现激光结构。在这里，我们希望系统地研究这些新结构。我们希望制备具有不同尺寸和形状的新型高定义贵金属纳米颗粒，并将其组装成具有表面晶格共振的周期性结构。它们将与合适的有机材料结合，并嵌入到高q分布布拉格反射器的腔中，以实现优异的激光特性，特别是高度光稳定的发射系统。与光子激光器/分布反馈激光器（DFB）类似，我们计划研究表面晶格共振（开腔设计/布拉格散射光反馈）与增益材料之间的相干能量传递。此外，我们计划探索机械可调的表面晶格共振。

In this project, we wish to realize a novel concept for organic nanoparticle lasers. The goal is to understand the lasing behavior of composite organic-nanoparticle cavities combining plasmonic surface lattice resonances with distributed Bragg reflectors. In preliminary work, we have shown that embedding metal nanoparticles and organic emitters into microcavities allows to realize laser structures. Here, we wish to systematically study these novel structures. We wish to prepare novel highly defined noble metal nanoparticles with varied size and shape and assemble them into periodic structures which show surface lattice resonances. They will be combined with suitable organic materials and embedded in high-Q distributed Bragg reflector-based cavities to achieve excellent lasing properties and in particular highly photostable emission systems. In analogy to a photonic laser/distributed feedback laser (DFB), we plan to study the coherent energy transfer between surface lattice resonance (open cavity design/optical feedback by Bragg scattering) and gain material. Furthermore, we plan to explore mechanically tunable surface lattice resonances.
