摘要

本研究探讨了量子通信网络中单光子发射器的发射增强，方法是将源与光学纳米纤维耦合，并利用金纳米粒子进行珀塞尔增强。最近的实验报道了Purcell增强超过50倍，但对重要问题的理解，包括最大Purcell因子，以及由于欧姆损失而限制的量子效率，仍然缺乏。我们的研究结果表明，报告的实验结果是合理的，并证实了这种复合器件为高效率的单光子源耦合到基于光纤的量子通信网络提供了一条有前途的途径。

Numerical investigation of plasmon-enhanced emission from a nanofiber coupled single photon emitter

This study explores the enhancement of emission from a single photon emitter in a quantum communication network by coupling the source with an optical nanofiber and leveraging gold nanoparticles for Purcell enhancement. Large Purcell enhancements of more than 50 times were recently reported experimentally, but understanding of important issues, including the maximum Purcell factor, and limits to quantum efficiency due to ohmic losses, is still lacking. Our findings reveal that the reported experimental results are reasonable, and confirm that such composite devices provide a promising route for high-efficiency single photon sources coupled to an optical fiber-based quantum communication network.
