Abstract

We present an ultra-thin source of down-converted photon pairs. These semiconductor-based devices are periodically poled to enhance generation efficiencies, yielding high-fidelity, maximally-entangled, tunable polarization states, without any walk-off compensation or interferometric techniques.
