In this paper, we demonstrate a source of photon pairs based onfour-wave-mixing in photonic crystal fibres. Careful engineering of the phasematching conditions in the fibres enables us to create photon pairs at 597 nmand 860 nm in an intrinsically factorable state showing no spectralcorrelations. This allows for heralding one photon in a pure state and hencerenders narrow band filtering obsolete. The source is narrow band, bright andachieves an overall detection efficiency of up to 21% per photon. For the firsttime, a Hong-Ou-Mandel interference with unfiltered photons from separate fibresources is presented.
