Ultratunable quantum frequency conversion in photonic crystal fiber
K. A. G. Bonsma-Fisher, P. J. Bustard, C. Parry +4
Quantum frequency conversion of single photons between wavelength bands is a key enabler to realizing widespread quantum networks. We demonstrate the quantum frequency conversion o…
All-fibre wavefront sensor
Thomas A. Wright, Stephanos Yerolatsitis, Kerrianne Harrington +2
We report on a tapered three-core optical fibre that can be used as a tip-tilt wavefront sensor. In this device, a coupled region of a few millimetres at the sensing tip of the fib…
Group-velocity symmetry in photonic crystal fibre for ultra-tunable quantum frequency conversion
Charlotte Parry, Philip B. Main, Thomas A. Wright +1
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…
Resource-efficient frequency conversion for quantum networks via sequential four-wave mixing
Thomas A. Wright, Charlotte Parry, Oliver R. Gibson +2
We report a resource-efficient scheme in which a single pump laser was used to achieve frequency conversion by Bragg-scattering four-wave mixing in a photonic crystal fiber. We dem…
Engineered photon-pair generation by four-wave mixing in asymmetric coupled waveguides
Robert. J. A. Francis-Jones, Thomas A. Wright, Andriy V. Gorbach +1
Third-order nonlinear processes require phase matching between the interacting fields to achieve high efficiencies. Typically in guided-wave platforms this is achieved by…
A two-way photonic interface for linking Sr+ transition at 422 nm to the telecommunications C-band
Thomas A. Wright, Robert J. A. Francis-Jones, Corin B. E. Gawith +7
We report a single-stage bi-directional interface capable of linking Sr+ trapped ion qubits in a long-distance quantum network. Our interface converts photons between the Sr+ emiss…
