- Abstract: Raman-scattering noise in silica has been the key obstacle toward the
realisation of high quality fiber-based photon-pair sources. Here, we
experimentally demonstrate how to get past this limitation by dispersion
tailoring a xenon-filled hollow-core photonic crystal fiber. The source
operates at room temperature, and is designed to generate Raman-free
photon-pairs at useful wavelength ranges, with idler at the telecom, and signal
at a visible range. We achieve a coincidence-to-accidentals ratio (2) as high
as 2740 combined with an ultra low heralded g H (0) = 0.002, indicating a very
high signal to noise ratio and a negligible multi-photon emission probability.
Moreover, by gas-pressure tuning, we demonstrate the control of photon
frequencies over a range as large as 13 THz, covering S-C and L telecom band
for the idler photon. This work demonstrates that hollow-core photonic crystal
fiber is an excellent platform to design high quality photon-pair sources, and
could play a driving role in the emerging quantum technology.
