A highly nonlinear (γ≈3700/W·m) silicon coupled-resonator-optical-waveguide generated heralded single photons (g(2)(0) ≤ 0.19 ±0.03) and widely-spaced photon pairs with coincidences-to-accidentals ratio >10 (cw) and >23 (pulsed), and outperformed a 54x longer silicon nanophotonic waveguide.

Telecommunications-band heralded single photons from a silicon nanophotonic chip

We demonstrate room temperature heralded single photon generation in a CMOS-compatible silicon nanophotonic device. The strong modal confinement and slow group velocity provided by a coupled resonator optical waveguide produced a large four-wave-mixing nonlinearity coefficient γeff≈4100 W−1 m−1 at telecommunications wavelengths. Spontaneous four-wave-mixing using a degenerate pump beam at 1549.6 nm created photon pairs at 1529.5 nm and 1570.5 nm with a coincidence-to-accidental ratio exceeding 20. A photon correlation measurement of the signal (1529.5 nm) photons heralded by the detection of the idler (1570.5 nm) photons showed antibunching with g(2)(0)=0.19±0.03. The demonstration of a single photon source within a silicon platform holds promise for future integrated quantum photonic circuits.We demonstrate room temperature heralded single photon generation in a CMOS-compatible silicon nanophotonic device.

We report a silicon-chip source of heralded single photons with extremely high quality, achieving a low conditional photon autocorrelation, gc(2) (0), of 0.0059±0.0016. The gc(2) (0) remains below 0.06 for photon flux up to 6.4 × 105 pair/s.
