Query: Silicon Photonic Entangled Photon-Pair and Heralded Single Photon
  Generation with CAR $>$ 12,000 and $g^{(2)}(0)<$ 0.006   We report measurements of time-frequency entangled photon pairs and heralded
single photons at 1550~nm wavelengths generated using a microring resonator
pumped optically by a diode laser. Along with a high spectral brightness of
pair generation, the conventional metrics used to describe performance, such as
Coincidences-to-Accidentals Ratio (CAR), conditional self-correlation
[$g^{(2)}(0)$], two-photon energy-time {F}ranson interferometric visibility
etc. are shown to reach a high-performance regime not yet achieved by silicon
photonics, and attained previously only by crystal, glass and fiber-based
pair-generation devices.
