本文分析了纳米柱单光子源中基模到辐射模的散射机制,证明其使收集效率与Purcell增强解耦并在失谐时达到最大收集效率,为未来单光子源设计提供指导。

摘要:

我们对支配纳米柱单光子源收集效率和Purcell增强的物理机制进行了详细分析。我们表明,标准的单模Fabry-Pérot模型不足以描述该器件的性能,其性能显著受益于从基模到辐射模的散射。我们展示了该散射机制如何将收集效率与Purcell增强解耦,从而在失谐条件下获得最大收集效率。最后,我们讨论了这种散射机制如何有利于未来的单光子源设计。

英文摘要:

We present a detailed analysis of the physics governing the collection efficiency and the Purcell enhancement of the nanopost single-photon source. We show that a standard single-mode Fabry-Pérot model is insufficient to describe the device performance, which benefits significantly from scattering from the fundamental mode to radiation modes. We show how the scattering mechanism decouples the collection efficiency from the Purcell enhancement, such that maximum collection efficiency is obtained off-resonance. Finally, we discuss how this scattering mechanism can be beneficial for future single-photon source designs.
