Abstract

Standard radio and microwave communication systems rely on the synchronization between a transmitter and a receiver, the information being carried by a periodic signal. The use of chaotic carriers instead of periodic ones constitutes both a natural extension of the procedure and a straightforward way of implementing spread-spectrum communication schemes. Given the current overwhelming interest on optical communication systems, nonlinear optical devices are the most suitable candidates to become the basic elements of chaotic communication setups. Recent years have witnessed the experimental demonstration of such setups, based on the synchronization between the dynamics of two lasers operating in a chaotic regime. Both fiber and diode lasers have been shown to be useful for that purpose [l].
