Chaos based communications using on-off shift keying method
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 couple...

| Sumario: | 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.
