Abstract
We designed, fabricated, and characterized a LiNbO3waveguide quasi-phase-matched highly nondegenerate twin photon generation device for a heralded single photon source. The power of the generated photon was nearly proportional to the pump power, as theoretically predicted. The temporal correlation of the generated twin photon was demonstrated by a photon coincidence counting experiment.
