We present experimental and numerical results of wavepacket expansion in one-dimensional disordered nonlinear waveguide arrays. We show that in 1D there is a direct transition from ballistic expansion to localization, which is accelerated by nonlinearity.
We demonstrate an adiabatic passage between uncoupled waveguides, in analogy with the quantum effects of STIRAP. In the nonlinear regime the associated adiabatic light passage is found to critically depend on the excitation power levels.
We present direct experimental measurements of localized eigenmodes in disordered one-dimensional waveguide arrays. In the nonlinear regime we observe delocalization of localized states, exhibiting different features in the limits of weak and strong disorder.

In this paper, we will introduce the concept of discrete solitons and we will discuss some of their spatio-temporal dynamics, which leads to interesting consequences in both the fundamental and the applied domain
We present experimental evidence for the formation of nonlinear X-waves in AlGaAs waveguide arrays. These results agree with numerical simulations based on the discrete nonlinear Schrodinger equation with an appropriate temporal dispersion term.
We investigate experimentally nonlinear effects near the photonic band edges of waveguide arrays. In this near resonant regime, due to the high curvature of the diffraction curves, nonlinearity results in strong beam shifts.
