Quasienergy band engineering and broadband dynamic localization inphotonic lattices with long-range interaction

摘要

Polychromatic dynamic localization in tight-binding lattices with long-range interaction is theoretically proposed and experimentally demonstrated in curved-waveguide photonic lattices. Efficient suppression of discrete diffraction over the whole white-light spectral region (450-750 nm) has been demonstrated in femtosecond-laser-written triangular-waveguide lattices with first- and second-order coupling.
