Fiber fly-overs are deployed for on-board optical interconnects in combination with on-board optical engines in different products such as high-performance switches for data centers. Polymer waveguides are a promising next step technology solution for integrated board-level optical connectivity to increase the interconnection density, their drawback is the high optical loss at key optical wavelengths...
We demonstrate a regenerative optomechanical oscillator operating at a high frequency of 375 MHz on lithium-niobate-on-insulator platform based upon a compact high-Q lithium niobate microdisk resonator with an intrinsic optical Qo of 2.2×105 and intrinsic mechanical Qm above 5000 in the air.
We report the highest raw quantum interference visibility for time-energy entangled photon pairs from a micron scale source, to date. Bi-photons from a silicon microdisk resonator were observed to have a raw coincidence visibility of (96.6 ± 1.1)%.
We develop an on-chip telecom-band single-photon source with Klyshko efficiencies up to 48%, the highest value for cavity-enhanced photon sources. For the first time, we relate Klyshko efficiency to high-order correlations and verify this relation experimentally.
We report the generation of high-purity twin photon pairs in a high-Q silicon microdisk resonator, with a pair flux of 5.31 × 10s pairs/s within a bandwidth of 0.73 GHz, and a high CAR as large as 155, the highest value reported to date for twin photon pairs.
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 selective mode splitting (SMS) in microresonators. SMS can split one selected optical mode up to 1.25 nm with other modes unperturbed. This opens a new gate for phasematching in parametric oscillations in microresonators.
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.
