title: Generation of energy-time entangled photon pairs in 1.5-mum 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.
