论文摘要
谐振荧光的光谱过滤被广泛用于通过消除不良背景来提高单个光子纯度和无法区分的性。对于接近发射极宽度的滤波器带宽，由于具有不同光子统计的组件的优先传输，因此可以预测复杂的行为。我们使用弱和强激发限制的purcell增强量子点探究了这种制度，与扩展的传感器理论模型找到了极好的一致性。通过仅更改滤波器宽度，可以在抗抗激素，束或泊松式之间转换光子统计。我们的结果证明，无法同时观察到强烈的抗抗挑战和亚自然线宽，从而提供了对相干散射本质的新见解。
Spectral filtering of resonance fluorescence is widely employed to improve single photon purity and indistinguishability by removing unwanted backgrounds. For filter bandwidths approaching the emitter linewidth, complex behaviour is predicted due to preferential transmission of components with differing photon statistics. We probe this regime using a Purcell-enhanced quantum dot in both weak and strong excitation limits, finding excellent agreement with an extended sensor theory model. By changing only the filter width, the photon statistics can be transformed between antibunched, bunched, or Poissonian. Our results verify that strong antibunching and a sub-natural linewidth cannot simultaneously be observed, providing new insight into the nature of coherent scattering.
