Abstract
We achieve ultrabroad quantum frequency conversion in a photonic crystal fiber, converting a 1,551 nm heralded single photon to one with wavelengths spanning the range 1,226 - 1,483 nm. We confirm non-classical timing correlations with the herald photon, and for conversion to 1,300 nm we measure a g(2)(0)t,t = 0.25(6).
