Impact of loss on the wave dynamics in photonic waveguide lattices (1408.5740v2)
Published 25 Aug 2014 in physics.optics
Abstract: We analyze the impact of loss in lattices of coupled optical waveguides and find that in such case, the hopping between adjacent waveguides is necessarily complex. This results not only in a transition of the light spreading from ballistic to diffusive, but also in a new kind of diffraction that is caused by loss dispersion. We prove our theoretical results with experimental observations.
