Abstract :
We have developed a vectorial quantum model of spontaneous parametric down-conversion in one-dimensional nonlinear photonic-band-gap structures. According to the obtained results these structures represent a promising perspective source of entangled two-photon states. In particular, entangled two-photon states antisymmetric in frequencies can be generated. Such entangled photons behave in the way resembling two fermions
