Diffraction-free image transmission in kagome photonic lattices
RA Vicencio, C Mejía-Cortés - Journal of Optics, 2013 - iopscience.iop.org
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 …

Stationary discrete solitons in a driven dissipative Bose-Hubbard chain
We demonstrate that stationary localized solutions (discrete solitons) exist in one-
dimensional Bose-Hubbard lattices with gain and loss in a semiclassical regime. Stationary …

Enhanced distribution of a wave-packet in lattices with disorder and nonlinearity
U Naether, S Rojas-Rojas, AJ Martínez, S Stützer… - Optics …, 2013 - opg.optica.org
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 …

Strain induced localization to delocalization transition on a Lieb photonic ribbon lattice
D Román-Cortés, G Fadic, C Cid-Lara… - Scientific Reports, 2021 - nature.com
Ribbon lattices are kind of transition systems in between one and two dimensions, and their
study is crucial to understand the origin of different emerging properties. In this work, we …
