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…
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…
