The future of quantum communications lies in the realization of repeaters for which a quantum memory is necessary and allows chaining multiple entanglement swappings. Such memories require photons with very narrow linewidths (< 100MHz), making it challenging to preserve the quality of entangled photon pair sources. Within this framework, we study the performances of twin photon sources based on spontaneous parametric down-conversion (SPDC) in nonlinear crystals. To allow for long-distance propagation, photons are created around 1550 nm and coupled into optical fibres. To anticipate synchronization requirements, we focus on pulsed sources. After studying the consequences of various degrees of freedom on the source performance, we make two co...
