Abstract :
In this work we consider the spatial analogous of temporal delay that is a two point nonlocality. This nonlocality couples each point in the transverse plane of a light beam with a shifted one and models the effects introduced by off-axis external feedback. The presence of tilted or off-axis beams is a common experimental issue and has also been subject of both theoretical and experimental study in liquid crystals light valves, Kerr-like media and generic nonlinear systems with diffusive and diffractive coupling. We discuss the effects of an off-axis feedback on the dynamics of lasers with fast decaying polarization, including media with negative refraction index and devices with soft apertures.
