    "abstract": "Photonic crystals create dramatic new possibilities for nonlinear optics.\nLine defects are shown to support modes suitable for the production of pairs of\nphotons by the material\u0027s second order nonlinearity even if the phase-matching\nconditions cannot be satisfied in the bulk. These structures offer the\nflexibility to achieve specific dispersion characteristics and potentially very\nhigh brightness. In this work, two phase matching schemes are identified and\nanalyzed regarding their dispersive properties.",
