Abstract: A photon pair generator includes a light source configured to emit light, and a nonlinear optical element configured to receive the light radiated from the light source and generate a quantum-entangled photon pair through spontaneous parametric down-conversion (SPDC), the nonlinear optical element including a polar material layer and a nonlinear material layer provided on the polar material layer.
