Diffraction-free image transmission in kagome photonic lattices
(2014)
We study the propagation of non-diffracting images in kagome photonic lattices. In a weak-coupling regime (discrete approach), the linear spectrum is composed by only three bands, including a completely degenerated and ...
Observation of a Localized Flat-Band State in a Photonic Lieb Lattice
(American Physical Society, 2015)
We demonstrate the first experimental realization of a dispersionless state, in a photonic Lieb lattice formed by an array of optical waveguides. This engineered lattice supports three energy bands, including a perfectly ...
Observation of localized ground and excited orbitals in graphene photonic ribbons
(IOP Publishing Ltd, 2018)
We report on the experimental realization of a quasi-one-dimensional photonic graphene ribbon supporting four flat-bands (FBs). We study the dynamics of fundamental and dipolar modes, which are analogous to the s and p ...
A simple method to construct Flat Band lattices
(American Physical Society, 2016)
We develop a simple and general method to construct arbitrary flat-band lattices. We identify the basic ingredients behind zero-dispersion bands and develop a method to construct extended lattices based on a consecutive ...
Bloch Floquet waves and localisation within a heterogeneous waveguide with long cracks
(2010)
A bi-material waveguide is assumed to have an array of sufficiently long cracks parallel to the boundaries. The BlochÂFloquet waves propagating along such a waveguide are dispersive, and the band gaps are clearly identified. ...
Diffractionfree image transmission in kagome photonic lattices
(IOP Publishing, 2014)
We study the propagation of non-diffracting images in kagome photonic lattices. In a
weak-coupling regime (discrete approach), the linear spectrum is composed by only three
bands, including a completely degenerated and ...
Experimental observation of bulk and edge transport in photonic Lieb lattices
(Deutsche Physikalische Gesellschaft, 2014)
We analyze the transport of light in the bulk and at the edge of photonic Lieb
lattices, whose unique feature is the existence of a flat band representing stationary
states in the middle of the band structure that can ...
Symmetry and localization properties of defect modes in magnonic superlattices
(American Physical Society, 2018-05)
Symmetry and localization properties of defect modes of a one-dimensional bicomponent magnonic superlattice are theoretically studied. The magnonic superlattice can be seen as a periodic array of nanostripes, where stripes ...
Characterization of multiple reflections and phase space properties for a periodically corrugated waveguide
(IOP PUBLISHING LTDBRISTOL, 2012)
Dynamical properties for a beam light inside a sinusoidally corrugated waveguide are discussed in this paper. The beam is confined inside two-mirrors: one is flat and the other one is sinusoidally corrugated. The evolution ...
