“…By omitting all loss mechanisms, the expected coincidence rate and pair brightness can be 4 orders of magnitude higher. Hence, the internal pair brightness at 1 mW reaches 2.82 ± 0.65 × 10 6 (s mW nm) −1 , which approaches the results of MRR-based sources in previous works [43][44][45][46] and is an order of magnitude higher than those using strip or slow-light enhanced waveguides [16,67,68]. The accidental coincidence counts follow N acc ∝ (N c + N n + d/η) 2 , where N n represents the photon contribution from the pump sideband noise, leaked pump field, and spontaneous Raman scattering.…”

We generate correlated photon pairs in an all-pass silicon microring resonator using continuous-wave pumped spontaneous four-wave mixing and we characterize in detail the optical bistability in the nonclassical single-photon regime. Special attention is given to the resonance-locked method by balancing the pump-induced heating and the active off-chip cooling, leading to stable operation of the photon-pair source. The maximal coincidence rate of 20.53 ± 0.34 Hz, maximal coincidence-to-accidental ratio of 654 ± 125, and minimal zero-delayed heralded second-order correlation of 0.14 ± 0.09 are achieved. The wavelengths of photon pairs remain unchanged at different pump power, indicating that our source is more compatible with the common communication systems than those using conventional on-resonance strategies, that tunes the pump wavelength. This work not only experimentally validates the nonclassical bistability behaviors, but also puts forward a simple method of pump-resonance matching for high-quality performance.

“…As a CMOS compatible material, silicon is extensively used for on-chip photon-pair sources via spontaneous fourwave mixing (SpFWM), due to the mature fabrication * guokai07203@hotmail.com procedure, low cost, and high material-based third-order nonlinear susceptibility [13][14][15]. By taking advantage of the high nonlinear refractive index and the submicronscale cross sections, silicon waveguides enable tight mode confinement and high nonlinearity [16].…”

Multichannel Photon-Pair Generation with Strong and Uniform Spectral Correlation in a Silicon Microring Resonator

et al. 2019

View full text Add to dashboard Cite

We experimentally demonstrate a photon-pair source, based on continuous-wave pumped spontaneous four-wave mixing in a silicon microring resonator, which efficiently generates photon pairs with high coincidence counts, high brightness, and high coincidence-to-accidental ratio at multiple resonance wavelengths matching a standard International Telecommunication Union (ITU) frequency grid. The signal-idler joint spectral intensity is measured with a very high resolution of 2 pm over multiple wavelengths by an optical spectrum analyzer through probe-swept stimulated four-wave mixing, allowing an accurate quantification of the spectral correlation. Strong spectral correlation and uniform degree of quantum correlation are observed from the source, and the measured amount of spectral modes agrees well with that obtained by unheralded second-order correlation measurements.

“…The correlated photon pairs are often used as herald single‐photon sources, where the second‐order correlation function value

g^{(2)} false(t false)

is an important evaluation index, which is expressed as

g^{(2)} false(t false) = N_{i s_{1} s_{2}} N_{i} / false(N_{i s_{1}} N_{i s_{2}} false)

. This value can be measured with a Hanbury Brown and Twiss setup (HBT), and an architecture is shown in Figure a.…”

The high stability and scalability of integrated circuits make them a reliable and practical platform for photonic quantum information processing. In various platforms for quantum photonic integrated circuits, the silicon‐on‐insulator technology, with its strong nonlinear effect and mature fabrication technology, has gradually emerged in the preparation of quantum photonic sources. This report presents a review of this series of research advances in the preparation of a quantum photonic source, based on the spontaneously four‐wave mixing process in a silicon waveguide, especially chip‐scale entangled states that have been realized in recent years.
