Generation of energy-time entangled photon pairs in 15-μm band with periodically poled lithium niobate waveguide

Abstract

We report the generation of 1.5-mm-band energy-time entangled photon pairs using a periodically poled lithium niobate (PPLN) waveguide. We performed a two-photon interference experiment and obtained coincidence fringes with 77.3% visibilities without subtracting accidental coincidences.

Generation of polarisation-entangled photon pairs at 1550 nm using two PPLN waveguides

Akio Yoshizawa, R. Kaji, Hidemi Tsuchida

Generation of polarisation-entangled photon pairs at 1550 nm is demonstrated using two periodically poled lithium niobate (PPLN) waveguides. In two-photon interference experiments, the coincidence detection rate was 0.53 kHz with a visibility of ∼94% (after subtraction of accidental coincidences). The ratio of single-photon to coincidence detection rate is ∼50.

Generation of time-bin entangled photon pairs by cascaded second-order nonlinearity in a single periodically poled LiNbO_3 waveguide

Myrtille O. J. Y. Hunault, Hiroki Takesue, Osamu Tadanaga +2 more

Entangled photon pairs are one of the most important resources for the development of quantum communication technologies. In order to produce pulsed photon pairs in the telecommunication band from 1.5 mum pump light, most of the previous experiments used two successive periodically poled lithium niobate (PPLN) waveguides. We report what we believe to be a new method using cascaded second-order nonlinearity in a single PPLN waveguide to produce high-purity time-bin entangled photon pairs. We confirmed the generation of entanglement through a two-photon interference experiment showing a coincidence fringe with a visibility of up to 97%.

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.

Generation of polarization-entangled photon pairs in 1550nm band by a fiber-optic two-photon interferometer

Akio Yoshizawa, Hidemi Tsuchida

Polarization-entangled photon pairs in a band around 1550nm are generated by use of a fiber-optic two-photon interferometer having two periodically poled lithium niobate waveguides. Coincidence measurements are adopted for feedback control, in order to suppress phase drifts in the state of entanglement. Two-photon interference with a visibility of ∼1 (after subtraction of accidental coincidences) is observed over an hour. The visibility including accidental coincidences is ∼0.77.
