We analyze the impact of loss in lattices of coupled optical waveguides and find that, in such a case, the hopping between adjacent waveguides is necessarily complex. This results not only in a transition of the ight spreading from ballistic to diffusive, but also in a new kind of diffraction that is caused by loss ispersion. We prove our theoretical results with experimental observations.
