The emission of light by coupled lasers is a fascinating scientific problem involving the fundamental concepts of coherence and chaos [1]. Such coupled nonlinear systems also lead naturally to new possibilities for optical communications [2]. Experimental and theoretical developments that show how one may utilize coupled chaotic systems for communication will be described [3].
