Abstract : The Grant partially funded an examination of photonic band structures. There were 2 invited talks and 5 publications. We report a new geometry based on stacking layers of dielectric rods; the dispersion curves reveal a large direct band gap. A collaborative experiment-theory effort was developed to characterize new two-dimensional structures with a band gap in the infrared. The lattice constant is three orders of magnitude smaller than all previous reports. Finally, a novel real-space numerical method was applied to one-dimensional structures; the technique can he extended to higher dimensions and it is useful for finite-sized systems and pulse propagation.
