摘要: We report the observation of quasiphase matched parametric fluorescence from a periodically poled silica fiber. A pair-photon production rate more than 100 MHz around 1532 nm was achieved in second-order nonlinear gratings for 300 mW pump power at 766 nm. These results are very promising realization reliable all-fiber single-photon sources quantum cryptography systems and metrology applications.
