High-performance single-photon generation with commercial-grade optical fiber

Physical Review A - Atomic, Molecular, and Optical Physics 83:3 (2011)

Authors:

C Söller, O Cohen, BJ Smith, IA Walmsley, C Silberhorn

Abstract:

High-quality quantum sources are of paramount importance for the implementation of quantum technologies. We present here a heralded single-photon source based on commercial-grade polarization-maintaining optical fiber. The heralded photons exhibit a purity of at least 0.84 and an unprecedented heralding efficiency into a single-mode fiber of 85%. The birefringent phase-matching condition of the underlying four-wave mixing process can be controlled mechanically to optimize the wavelength tuning needed for interfacing multiple sources, as is required for large-scale entanglement generation. © 2011 American Physical Society.
