Generating telecom-band pure heralded single photons on a silica chip
Single photon sources are a key building block for quantum information processing. A common approach uses spontaneous emitters based on parametric down conversion and four wave mixing. In 2005 experiments on the first spectrally engineered four wave mixing sources in fibre were published [1,2]. A primary obstacle for photonics to realize quantum-enhanced applications is loss. Designing single photon sources matched to single mode optical fibres greatly reduces coupling losses [3]. In addition, tailoring the phase matching properties of the sources to generate factorable photon pairs makes strong spectral filtering obsolete and thereby avoids the degradation of photon number correlations due to loss.

Abstract
Single photon sources are a key building block for quantum information processing. A common approach uses spontaneous emitters based on parametric down conversion and four wave mixing. In 2005 experiments on the first spectrally engineered four wave mixing sources in fibre were published [1,2]. A primary obstacle for photonics to realize quantum-enhanced applications is loss. Designing single photon sources matched to single mode optical fibres greatly reduces coupling losses [3]. In addition, tailoring the phase matching properties of the sources to generate factorable photon pairs makes strong spectral filtering obsolete and thereby avoids the degradation of photon number correlations due to loss.
