Dynamic localization and self-imaging effects in waveguide arrays with periodically-bent axis

In this contribution we propose to use an array of lithium niobate optical waveguides with periodically-curved axis to observe the phenomenon of dynamic localization. We show the equivalence of the optical problem with the electron dynamics and study the general conditions to obtain dynamic localization. We extend the analysis to include nonlinear (Kerr) effects as well and predict, under the condition for self-imaging in the linear propagation regime, a strong suppression of nonlinear interaction as well. In particular, we prove inhibition of modulational instability in the periodically-curved waveguide array
