Observation of higher-order solitons in defocusing waveguide arrays
Eugene Smirnov, Christian E. Ruter, Detlef Kip +2
We observe experimentally higher-order solitons in waveguide arrays with defocusing saturable nonlinearity. Such solitons can comprise several in-phase bright spots and are stable…

Beam interactions in one-dimensional saturable waveguide arrays
Milutin Stepic, Eugene Smirnov, Christian E. Rueter +2
The interaction between two parallel beams in one-dimensional discrete saturable systems has been investigated using lithium niobate nonlinear waveguide arrays. When the beams are…
