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.
