Photon pair generation using four-wave mixing in a microstructured fibre: theory versus experiment

, 2006
We develop a theoretical analysis of four-wave mixing used to generate photon pairs useful for quantum information processing. The analysis applies to a single mode microstructured fibre pumped by an ultra-short coherent pulse in the normal dispersion ...
