High visibility two photon interference of frequency time entangled photons generated in a quasi phase matched AlGaAs waveguide

Abstract

We demonstrate experimentally the frequency time entanglement of photon pairs produced in a CW pumped quasi phased matched AlGaAs superlattice waveguide. A visibility of 96.0+-0.7% without background subtraction has been achieved, which corresponds the violation of Bell inequality by 52 standard deviations.
