Inhalt:
We demonstrate an unprecedentedly bright heralded single-photon source with ideal single photon purity and proposed an explicit theoretical limit of purity of heralded single-photon sources. The measured coincidence rate exceeds 1.5 MHz, and the lowest g(2) h (0) is 0.000945 which has never achieved by on-chip SFWM sources.
