Abstract

We pump two periodically-poled lithium niobate waveguides of different lengths in a Sagnac loop to produce photons with spectrally-varying non-maximal polarization entanglement for the first time. The desired non-maximality is selectable by optical wavelength filtering.

The generation of polarization-entangled photon pairs using periodically poled lithium niobate waveguides in a fibre loop

Yun-Kun Jiang, Akihisa Tomita

We report the generation of polarization-entangled photon pairs at a telecom band using two cascade periodically poled lithium niobate waveguides in a fibre loop. The phase of an entangled photon state was stabilized automatically in our setup. The average visibility was about 93.5 ± 2.6% for the entangled photon pairs after subtracting accidental coincidences in our measurement.

Wavelength-multiplexed distribution of highly entangled photon-pairs over optical fiber

We report the first experimental demonstration of wavelength-multiplexed entanglement distribution over optical fiber. Forty-four channels of polarization-entangled photon-pairs were produced from a single pulse-pumped, short periodically-poled lithium niobate waveguide and distributed over 10 km of dispersion-shifted optical fiber. Entanglement fidelities of the distributed photon-pairs exceeded 0.86 for all selected channels.
