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…

Parametric Resonances and Resonant Delocalization in Quasi-Phase Matched Photon-pair Generation and Quantum Frequency Conversion
Philip B. Main, Peter J. Mosley, Andrey V. Gorbach
The existing widely-accepted theory of photon-pair generation via spontaneous down-conversion (SPDC) in nonlinear optical crystals and waveguides is incomplete, as it fails to acco…
