**Dynamic Localization of Photons in Sinusoidally-Curved Waveguide Arrays** - Mirko Lobino

The electron motion in a crystalline potential subjected to an
external sinusoidal electric field reveals an interesting coherent
dynamical phenomenon called dynamic localization (DL). This phenomenon
consists of a periodic relocalization of the electronic wave function
under the action of an external field with proper amplitude and frequency,
as it was theoretically predicted by Dunlap and Kenkre in 1986. Curved
waveguide arrays provide an ideal laboratory system for visualizing DL
since the paraxial wave equation for the electromagnetic field is formally
identical to the Schrödinger equation for the electron wavefunction in a
periodic potential under the action of an external field.
