Abstract

We introduce a cellular automata methodology for studying the photonics of light-induced phase transitions. A model governed by a sparse set of evolutionary rules successfully describes the complex, non-stationary, spatially inhomogeneous dynamics and nonlinear optical properties of a medium undergoing a light-induced structural transition.
