Compactification tuning for nonlinear localized modes in sawtooth lattices
Magnus Johansson, Uta Naether, Rodrigo A. Vicencio
We discuss the properties of nonlinear localized modes in sawtooth lattices, in the framework of a discrete nonlinear Schrödinger model with general on-site nonlinearity. Analytic…
Self-trapping transition in nonlinear cubic lattices
Uta Naether, Alejandro J. Martínez, Diego Guzmán-Silva +2
We explore the fundamental question of the critical nonlinearity value needed to dynamically localize energy in discrete nonlinear cubic (Kerr) lattices. We focus on the effective…
Mobility of high-power solitons in saturable nonlinear photonic lattices
Uta Naether, Rodrigo A. Vicencio, Milutin Stepić
We theoretically study the properties of one-dimensional nonlinear saturable photonic lattices exhibiting multiple mobility windows for stationary solutions. The effective energy b…
Peierls-Nabarro energy surfaces and directional mobility of discrete solitons in two-dimensional saturable nonlinear Schrödinger lattices
Uta Naether, Rodrigo A. Vicencio, Magnus Johansson
We address the problem of directional mobility of discrete solitons in two-dimensional rectangular lattices, in the framework of a discrete nonlinear Schrödinger model with saturab…
Fano resonances in saturable waveguide arrays
Uta Naether, Daniel E. Rivas, Manuel A. Larenas +2
We study a waveguide array with an embedded nonlinear saturable impurity. We solve the impurity problem in closed form and find the nonlinear localized modes. Next, we consider the…
