预示的单表面等离子激元极化子是由自发参数下转换产生的光子激发的。研究了平均激发率、强度相关性和Fock态居群。我们在实验中观察到的二阶相干的依赖性与量子状态下线性不相关的马尔可夫环境是一致的。我们的研究结果为评估等离子体波导在量子体制下用于纳米光子电路的潜力提供了关于损耗影响的重要信息。
Heralded single surface plasmon polaritons are excited using photons generated via spontaneous parametric down conversion. The mean excitation rates, intensity correlations, and Fock state populations are studied. The observed dependence of the second-order coherence in our experiment is consistent with a linear uncorrelated Markovian environment in the quantum regime. Our results provide important information about the effect of loss for assessing the potential of plasmonic waveguides for future nanophotonic circuitry in the quantum regime.
