Applying an external driving to a periodic potential drastically modifies both propagation and localization of waves. One important example is dynamic localization (DL), the suppression of broadening of a wave packet during its motion in a periodic potential under the action of an externally applied periodic field . The same effect can occur for optical beams in curved waveguide arrays, where the waveguide bending [see Fig. 1(a)] mimics the effects of the driving field, leading to the...[Show more]
