Performance of the nanopost single-photon source: beyond the single-mode model

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-Perot 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.

Automated summary

In this paper, we provide a detailed analysis of the physics behind the collection efficiency and Purcell enhancement of the nanopost single-photon source. We find that a standard single-mode Fabry-Perot model is insufficient to explain the device performance, as scattering from the fundamental mode to radiation modes plays a significant role. We also discover that the scattering mechanism decouples the collection efficiency from the Purcell enhancement, leading to maximum collection efficiency off-resonance. Lastly, we discuss the potential benefits of this scattering mechanism for future single-photon source designs.
