Naether, Uta; Rojas Rojas, Santiago; Martínez, Alejandro J.; Stützer, Simon; Tünnermann, Andreas; Nolte, Stefan; Molina Gálvez, Mario; Vicencio Poblete, Rodrigo; Szameit, Alexander (Optical Society of America, 2013-01)We show, numerically and experimentally, that the presence of weak disorder results in an enhanced energy distribution of an initially localized wave-packet, in one- and two-dimensional finite lattices. The addition of ...

Vicencio Poblete, Rodrigo; Cantillano, Camilo; Morales Inostroza, Luis; Real, Bastián; Mejía Cortés, Cristian; Weimann, Steffen; Szameit, Alexander; Molina Gálvez, Mario (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 ...

Szameit, Alexander; Molina Gálvez, Mario; Heinrich, Matthias; Dreisow, Felix; Keil, Robert; Nolte, Stefan; Kivshar, Yuri S. (OPTICAL SOC AMER, 2010-08-15)We study experimentally light localization at phase-slip waveguides and at the intersection of phase-slips in a two-dimensional (2D) square photonic lattice. Such system allows to observe a variety of effects, including ...
