    "abstract": "We report on the experimental realization and characterization of an\nasynchronous heralded single photon source based on spontaneous parametric down\nconversion. Photons at 1550nm are heralded as being inside a single-mode fiber\nwith more than 60% probability, and the multi-photon emission probability is\nreduced by up to a factor 600 compared to poissonian light sources. These\nfigures of merit, together with the choice of telecom wavelength for the\nheralded photons are compatible with practical applications needing very\nefficient and robust single photon sources.",
