1.5-μm Narrow-Band Two-Photon Source for Long-Distance Quantum Communication

We demonstrate a narrow-band telecom two-photon source for long-distance quantum communication. The second-order cross-correlation function reveals narrow linewidth of 2.4 MHz and the highest spectral brightness of3.94 × 105 pairs/(s.MHz.mW).
