    "abstract": "We have developed a rigorous quantum model of spontaneous parametric\ndown-conversion in a nonlinear 1D photonic-band-gap structure based upon\nexpansion of the field into monochromatic plane waves. The model provides a\ntwo-photon amplitude of a created photon pair. The spectra of the signal and\nidler fields, their intensity profiles in the time domain, as well as the\ncoincidence-count interference pattern in a Hong-Ou-Mandel interferometer are\ndetermined both for cw and pulsed pumping regimes in terms of the two-photon\namplitude. A broad range of parameters characterizing the emitted\ndown-converted fields can be used. As an example, a structure composed of 49\nlayers of GaN/AlN is analyzed as a suitable source of photon pairs having high\nefficiency.",
