High quality asynchronous heralded single photon source at telecom wavelength. 5 m is experimentally demonstrated based on sponta-neous four wave-mixing in a piece of dispersion-shifted fiber cooled by We show that with spectral filtering to preserve nearly 90% of the photon pairs, this source can be used as an efficient, heralded, pure-state single-photon source. We report on the experimental realization and characterization of an asynchronous heraldedsingle-photon source based on spontaneous parametric down-conversion. Nov 13, 2024 · In this work, we demonstrate an on-chip pair generation rate of up to 3. High-quality asynchronous heralded single-photon source at telecom wavelength These figures of merit, together with the choice of telecom wavelength for the heralded photons, are compatible with practical applications needing very efficient and robust single-photon sources. Nov 12, 2004 · We report on the experimental realization and characterization of an asynchronous heralded single-photon source based on spontaneous parametric down-conversion. 6 View the article online for updates and enhancements. 1 MHz by a spontaneous four-wave mixing process in a hydrogenated amorphous silicon (a-Si:H) waveguide using a continuous-wave (CW) laser. Photons at 1550nm are heralded as being inside a single-mode fibre with more than 60% probability, and themulti-photon emission probability is reduced by a factor of up to more than 500 compared toPoissonianlightsources We report on the experimental realization and characterization of an asynchronous heralded single photon source based on spontaneous parametric down conversion. By performing a heralded autocorrelation measurement, we show that even for high levels of pair generation, the source keeps emitting light in the single-photon regime.
