Rezumat

We discuss the dynamical behavior of a single mode semiconductor laser under the in- fluence of multiple optical feedbacks. It is shown that the system displays, under certain conditions, chaotic behaviors appropriate for chaos based communications. The synchronization of two unidirectional coupled (master-slave) systems is also studied. Finally, the conditions for message encoding by using the on/off phase shift keying encryption method are identified and examples of message encoding/decoding are presented.
