Discrete gap solitons in binary positive-negative index nonlinear waveguide arrays with strong second-order couplings
Alexander A. Dovgiy, Ilya S. Besedin
We report on existence and properties of discrete gap solitons in zigzag arrays of alternating waveguides with positive and negative refractive indices. Zigzag quasi-one-dimensiona…

Modulation instability in nonlinear positive-negative index waveguide array
A. A. Dovgiy, A. I. Maimistov
Modulation instability in a nonlinear optical waveguide array with alternating positive and negative refractive indices is investigated analytically. Particular solutions of a syst…
