    "abstract": "An exactly-solvable model for the decay of a metastable state coupled to a\nsemi-infinite tight-binding lattice, showing large deviations from exponential\ndecay in the strong coupling regime, is presented. An optical realization of\nthe lattice model, based on discrete diffraction in a semi-infinite array of\ntunneling-coupled optical waveguides, is proposed to test non-exponential decay\nand for the observation of an optical analog of the quantum Zeno effect.",
