- Abstract: Quantum frequency conversion of single photons between wavelength bands is a
key enabler to realizing widespread quantum networks. We demonstrate the
quantum frequency conversion of a heralded 1551 nm photon to any wavelength
within an ultrabroad (1226 - 1408 nm) range in a group-velocity-symmetric
photonic crystal fiber (PCF), covering over 150 independent frequency bins. The
target wavelength is controlled by tuning only a single pump laser wavelength.
We find internal, and total, conversion efficiencies of 12(1)% and 1.4(2)%,
respectively. For the case of converting 1551 nm to 1300 nm we measure a
heralded $g^{(2)}(0) = 0.25(6)$ for converted light from an input with
$g^{(2)}(0) = 0.034(8)$. We expect that this PCF can be used for a myriad of
quantum networking tasks.

We introduce a photonic crystal fiber with a germanium-doped core featuring group velocity matching at 1550 nm, the telecoms C-band, and 920 nm.
Large lengths of this fiber are used to achieve nanometer-scale frequency shifts between wavelengths around 920 nm with up to 79.4% internal conversion efficiency.
