    "abstract": "We develop a theoretical analysis of four-wave mixing used to generate photon\npairs useful for quantum information processing. The analysis applies to a\nsingle mode microstructured fibre pumped by an ultra-short coherent pulse in\nthe normal dispersion region. Given the values of the optical propagation\nconstant inside the fibre, we can estimate the created number of photon pairs\nper pulse, their central wavelength and their respective bandwidth. We use the\nexperimental results from a picosecond source of correlated photon pairs using\na micro-structured fibre to validate the model. The fibre is pumped in the\nnormal dispersion regime at 708nm and phase matching is satisfied for widely\nspaced parametric wavelengths of 586nm and 894nm. We measure the number of\nphotons per pulse using a loss-independent coincidence scheme and compare the\nresults with the theoretical expectation. We show a good agreement between the\ntheoretical expectations and the experimental results for various fibre lengths\nand pump powers.",
