Title: Group-velocity symmetry in photonic crystal fibre for ultra-tunable quantum frequency conversion
Authors: Charlotte Parry, Philip B. Main, Thomas A. Wright and Peter J. Mosley
Abstract summary: We show that a single photonic crystal fibre can achieve frequency conversion by Bragg-scattering four-wave mixing of source photons from an ultra-broad wavelength range. This enables a single highly adaptable frequency conversion interface to link disparate nodes in a quantum network via the telecoms band.

Abstract: Low-noise frequency conversion of single photons is a critical tool in establishing fibre-based quantum networks. We show that a single photonic crystal fibre can achieve frequency conversion by Bragg-scattering four-wave mixing of source photons from an ultra-broad wavelength range by engineering a symmetric group velocity profile. Furthermore, we discuss how pump tuning can mitigate realistic discrepancies in device fabrication. This enables a single highly adaptable frequency conversion interface to link disparate nodes in a quantum network via the telecoms band.
