High-Purity Telecom-Band Entangled Photon-Pairs via Four-Wave Mixing in Dispersion-Shifted Fiber
K. F. Lee, J. Chen, C. Liang +3
We have studied the purity of entangled photon-pairs generated in a dispersion-shifted fiber at various temperatures. Two-photon interference with visibility > 98% is observed at 7…

An integrable optical-fiber source of polarization entangled photon-pairs in the telecom band
Xiaoying Li, Chuang Liang, Kim Fook Lee +3
We demonstrate an optical-fiber based source of polarization entangled photon-pairs with improved quality and efficiency, which has been integrated with off-the-shelf telecom compo…

Quantum-noise--randomized data-encryption for WDM fiber-optic networks
Eric Corndorf, Chuang Liang, Gerg S. Kanter +2
We demonstrate high-rate randomized data-encryption through optical fibers using the inherent quantum-measurement noise of coherent states of light. Specifically, we demonstrate 65…
