Analytical model for waveguide light propagation and applications
Santiago Rojas Rojas, Luis Morales-Inostroza, Uta Naether +6
We study the polarization properties of elliptical femtosecond-laser-written waveguides arrays. A new analytical model is presented to explain the asymmetry of the spatial transver…
Multi-stable regime and intermediate solutions in a nonlinear saturable coupler
Diego Guzmán-Silva, Cibo Lou, Uta Naether +3
We show, theoretically and experimentally, the existence of a multi-stable regime in a nonlinear saturable coupler. In spite of its simplicity, we found that this model shows gener…
Expansion of a wave-packet in lattices with disorder and nonlinearity
Uta Naether, Santiago Rojas-Rojas, Alejandro J. Martinez +6
We show, theoretically and experimentally, the counterintuitive result that an increase of disorder can result in an enhanced spreading of an initially localized excitation. Moreov…
Observation of the gradual transition from one-dimensional to two-dimensional Anderson localization
U. Naether, Y. V. Kartashov, V. A. Vysloukh +4
We study the gradual transition from one-dimensional to two-dimensional Anderson localization upon transformation of the dimensionality of disordered waveguide arrays. An effective…
Nonlinear localized modes in Glauber-Fock photonic lattices
Alejandro J. Martínez, Uta Naether, Alexander Szameit +1
We study a nonlinear Glauber-Fock lattice and the conditions for the excitation of localized structures. We investigate the particular linear properties of these lattices, includin…
Fano resonances in magnetic metamaterials
Uta Naether, Mario I. Molina
We study the scattering of magnetoinductive plane waves by internal (external) capacitive (inductive) defects coupled to a one-dimensional split-ring resonator array. We examine a…
