We present numerical simulations describing the dynamics of two multisection semiconductor lasers emitting in a chaotic regime coupled in a master-slave configuration. By changing the current of the passive section of the master laser we observe a change in the maximum correlation between the outputs of the two systems. These devices are promising candidates for on/off phase shift keying encryption.
