Abstract

In non-Hermitian open quantum systems, such as polariton condensates, the local tailoring of gains and losses opens up an interesting possibility to realize functional optical elements. Here, we demonstrate that deliberately introducing losses via a photonic defect, realized by reducing the quality factor of a DBR mirror locally within an ultrahigh-quality microcavity, may be utilized to create directed polariton currents towards the defect. We discuss the role of polariton-polariton interactions in the process and how to tailor the effective decay time of a polariton condensate by coupling it to the defect. Our results highlight the far-reaching potential of non-Hermitian physics in polaritonics.

通过定制光子缺陷的定向极化子流

在极化子凝聚体等非赫米提开放量子系统中，增益和损耗的局部定制为实现功能性光学元件提供了有趣的可能性。在这里，我们展示了通过光子缺陷故意引入损耗，在超高质量微腔中局部降低 DBR 镜面的品质因数来实现，可用于产生指向缺陷的定向极化子电流。我们讨论了极化子-极化子相互作用在这一过程中的作用，以及如何通过与缺陷耦合来调整极化子凝聚态的有效衰减时间。我们的研究结果凸显了非赫米提物理学在极化中的深远潜力。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
