Correlated Photon-Pair Generation in Reverse Proton-Exchange PPLN Waveguides With Integrated Mode Demultiplexer at 10 GHz Clock

Abstract

We report 10-ps correlated photon pair generation in periodically-poled reverse-proton-exchange lithium niobate waveguides with integrated mode demultiplexer at a wavelength of 1.5-micron and a clock of 10 GHz. Using superconducting single photon detectors, we observed a coincidence to accidental count ratio (CAR) as high as 4000. The developed photon-pair source may find broad application in quantum information systems as well as quantum entanglement experiments.
