• Authors: Martin Arentoft Jacobsen, Yujing Wang, Luca Vannucci, Julien Claudon, Jean-Michel G\'erard, and Niels Gregersen
• Abstract summary: We present a detailed analysis of the physics governing the collection efficiency and the Purcell enhancement of the nanopost single-photon source. We show how the scattering mechanism decouples the collection efficiency from the Purcell enhancement, such as maximum collection efficiency is obtained off-resonance.

• Abstract: 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-P\'erot 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.

  Fluorescence collection from individual emitters plays a key role in state detection and remote entanglement generation. Planar photonics have been demonstrated for robust and scalable addressing of trapped-ion systems. We show that far-field photon collection efficiency can be simply expressed in terms of the fields associated with the collection optic at the emitter position alone.
