具有高光谱时间纯度的单光子是量子光子技术的重要资源。迄今为止，传统硅光子器件报道的最高纯度为92%，无需任何光谱滤波。我们使用传统的微赛道谐振器和设计的双泵脉冲，实验产生并观察到光谱时间纯度为98.0±0.3%的单光子，这是受激发射断层扫描的上限。
Single-photons with high spectro-temporal purity are an essential resource for quantum photonic technologies. The highest reported purity up until now from a conventional silicon photonic device is 92% without any spectral filtering. We have experimentally generated and observed single-photons with 98.0±0.3% spectro-temporal purity, an upper bound of the stimulated emission tomography, using a conventional micro-racetrack resonator and an engineered dual pump pulse.
