Photonic flat band dynamics

During the last decades, researchers of different scientific areas have investigated several systems and materials to suggest new ways transporting localizing light. These problems are probably main goals in any search for configurations emerging properties, independently degree complexity suggested methods. Fortunately, fabrication techniques photonics consolidated during allowing experimental implementation theoretical ideas which were neither tested nor validated. Specifically, we will focus on recent advances Flat Band (FB) photonic systems. FB periodical structures at least two bands their linear spectrum, with one them completely flat. This implies emergence states localized space that can be located regions across lattice. localization occurs as a result destructive interference, what naturally depends particular lattice geometry. In addition, flat band also posses dispersive make possible observation ballistic transport well. Therefore, lattices constitute an unique platform studying transport, without requiring inclusion sophisticated interaction/effect, rather smart simple
