Semiconductor lasers in the presence of weak external optical injection or feedback become unstable, exhibiting optical chaos. I use a multi longitudinal mode partial differential equation model to study many physically observable phenomenon. These include longitudinal mode hops induced by weak external injection and anti-phase dynamics among the longitudinal modes in the presence of weak feedback. Chaotic semiconductor lasers are shown to be good candidates for optical communication: synchronization is robust and messages may be multiplexed through the many longitudinal modes.Type
