Single-shot measurement of photonic topological invariant
Nathan Roberts, Guido Baardink, Anton Souslov +1
Topological design enables robustness to be engineered into a system. However, a general challenge remains to experimentally characterize topological properties. In this work, we d…
Topological supermodes in photonic crystal fiber
Nathan Roberts, Guido Baardink, Josh Nunn +2
Topological states enable robust transport within disorder-rich media through integer invariants inextricably tied to the transmission of light, sound, or electrons. However, the c…
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…
Discrete Diffraction for Spectral Purification in Spontaneous Four Wave Mixing: a Recipe
Philip B. Main, Peter J. Mosley, Andrey V. Gorbach
Linear discrete diffraction of light within a waveguide array allows control over the longitudinal spatial profile of light. We propose a method of using this control to effectivel…
Spontaneous Parametric Down-Conversion in asymmetric couplers: photon purity enhancement and intrinsic spectral filtering
Philip B. Main, Peter J. Mosley, Andrey V. Gorbach
We analyze the process of photon-pair generation via spontaneous parametric down-conversion in a quadratic nonlinear asymmetric waveguide coupler. The two waveguides have different…
Passive, broadband and low-frequency suppression of laser amplitude noise to the shot-noise limit using hollow-core fibre
Euan J. Allen, Giacomo Ferranti, Kristina R. Rusimova +6
We use hollow-core fibre to preserve the spectrum and temporal profile of picosecond laser pulses in CBD to suppress 2.6 dB of amplitude noise at MHz noise frequencies, to within 0…
