# High coherence photon pair source for quantum communication

 Authors: M Halder, A Beveratos, R T Thew, C Jorel, H Zbinden, N Gisin New Journal of Physics 10, 023027 (2008) http://dx.doi.org/10.1088/1367-2630/10/2/023027 This paper reports a novel single mode source of narrow-band entangled photon pairs at telecom wavelengths under continuous wave (CW) excitation, based on parametric down conversion. For only 7mW of pump power it has a created spectral radiance of 0.08 pairs per coherence length and a bandwidth of 10 pm (1.2 GHz). The effectively emitted spectral brightness reaches 3.9 x 10(5) pairs s(-1) pm(-1). Furthermore, when combined with low jitter single photon detectors, such sources allow for the implementation of quantum communication protocols without any active synchronization or path length stabilization. A Hong-Ou-Mandel (HOM)-dip with photons from two autonomous CW sources has been realized demonstrating the setup's stability and performance. njphalder08.pdf
