Experimental demonstration of rogue waves in disordered Luneburg-type photonic networks

Here we investigate the case of extreme waves in disordered Luneburg-type photonic networks both theoretically and experimentally. We present characteristic theoretical and experimental results, which clearly demonstrate the existence of such events. We observe this phenomenon in the linear optics regime. We shall discuss the conditions under which rogue waves can be observed in our system, while we will also discuss the relative role between linear and nonlinear contributions.
