Abstract

Chaotic behavior is a common feature of mechanical, electrical, optical or other kind of systems. If a certain device, described by a group of mathematical relations with input and output variables and depending on parameters, is stimulated with a known deterministic signal, then its output can behave randomly in some conditions. If two identical or slightly different systems are interconnected together in such way that the input of the second is fed by the output of the first, then a synchronization effect can occur between the outputs of the two devices. Particularly, in the field of optical communication, a number of systems in which the information signal is send from modulator to demodulator through a chaotic carrier and in the same time masked by it, can be imagined. This paper analyses the potential use of Self Pulsating Laser Diodes (SPLD) in an amplitude modulation scheme able to make a data link with preservation of information secrecy.
