Abstract
An experimental realization of an optical ''kicked'' system is presented. I t exhibits localization analogous to that of the quantum "kicked-rotor." In the experiment, free space propagating light is periodically kicked by thi n sinusoidal phase gratings, which produce high order diffractions and tend to increase the spatial frequency band. The wave property suppresses this diffusive spread. The localization is realized in a regime near antiresonan ce of the system, which is also studied theoretically. The behavior in this regime is similar to that of electronic motion in incommensurate potential s. A crucial part of the experimental system is the grating in-phase positi oning, which is done by using the Talbot effect.
