摘要：

We demonstrate the possibility of using periodically poled lithium niobate crystals (PPLN) as a direct source of entangled photon pairs. Two configurations are studied. The first enables the generation of polarization-entangled states from a one-dimensional PPLN structure at different frequencies; the second is dedicated to the production of frequency-entangled states from a bi-dimensional PPLN structure. The engineering of both of these PPLN structures are described from a theoretical perspective.
