Improving the spectral purity of single photons by a single-interferometer-coupled microring

文献摘要：

We experimentally engineer a high-spectral-purity single-photon source using a single-interferometer-coupled silicon microring.By the reconfiguration of the interferometer,different coupling conditions can be obtained,corresponding to different quality factors for the pump and signal/idler.The ratio between the quality factor of the pump and signal/idler ranges from 0.29 to 2.57.By constructing the signal-idler joint spectral intensity,we intuitively demonstrate the spectral correlation of the signal and idler.As the ratio between the quality factor of the pump and signal/idler increases,the spectral correlation of the signal and idler decreases,i.e.,the spectral purity of the signal/idler photons increases.Furthermore,time-integrated second-order correlation of the signal photons is measured,giving a value up to 94.95±3.46％.Such high-spectral-purity photons will improve the visibility of quantum interference and facilitate the development of on-chip quantum information processing.
