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 to the violation of the Bell inequality by 52 standard deviations.
