    "abstract": "Linear defect modes in one-dimensional photonic lattices are studied\ntheoretically. For negative (repulsive) defects, various localized defect modes\nare found. The strongest confinement of the defect modes appear when the\nlattice intensity at the defect site is {\\em non-zero} rather than zero. When\nlaunched at small angles into such a defect site of the lattice, a Gaussian\nbeam can be trapped and undergo snake oscillations under appropriate\nconditions.",
