概　要	We experimentally demonstrate frequency translation of a nonclassical optical field via four-wave mixing (nonlinear-optical Bragg scattering) in a photonic crystal fiber (PCF). The high nonlinearity and the ability to control dispersion in PCF enable efficient translation between nearby photon channels within the visible to-near-infrared spectral range, useful in quantum networks for allowing systems (atoms, ions, cavities, fibers, detectors) operating at different wavelengths to “talk” with each other. Experiment shows efficient translation of heralded single- photons (produced separately in PCF) from wavelength 683 nm to 659 nm, while maintaining photon statistics in the non-classical regime.
