Abstract

We investigate the interplay between two fundamentally different localization mechanisms in discrete systems: dynamic localization, i.e., resonant wave packet revivals in periodically driven lattices, and Anderson localization, the suppression of transverse transport in the presence of disorder. Using curved femtosecond laser-written photonic lattices as the experimental platform, we directly observe the propagation dynamics for varying degrees of diagonal disorder and characterize the transition between the two regimes of localization.
