Highly efficient photon-pair source using a Periodically Poled Lithium Niobate Waveguide

S. Tanzilli, H. de Riedmatten, W. Tittel +5

We report on a new kind of correlated photon-pair source based on a waveguide integrated on a Periodically Poled Lithium Niobate substrate. Using a pump laser of a few micro-Watts…
