We report ultra-pure single-mode photon generation through four-wave mixing in high-Q silicon microdisks. The cross correlation of photon pairs peaks over 25,000 and the self correlations of both photon modes peak around 1.8.
We demonstrate a convenient approach for precise dispersion engineering of silicon microdisk resonators via thermal oxidation. This technique potentially enables efficient correlated photon-pair generation for quantum photonics.
We demonstrate compact silicon microring resonators suspended in air with ultra-high optical quality, achieving an intrinsic quality factor of 9.2×105 in the telecom band for the resonator with a radius of 9 µm.
We demonstrate an on-chip single photon source that produces ultra-bright high-purity photon pairs in a comb fashion, achieving a spectral brightness of 6.24×107 pair/s/mW2/GHz which is the highest performance reported up to date.
We demonstrate a novel approach for trapping mechanical motion and elastic tuning of mechanical rigidity while preserving phonon number, through a giant quadratic optomechanical coupling created from a tunable coupled microdisk resonator.
