The realization of chaotic synchronization has given rise to a new secure communication technology: chaotic secure optical communication using chaotic signals as information carriers. In 1998, Gregory D. Vanwiggeren and Rajarshi Roy experimentally validated the feasibility of chaotic secure optical communication. By using chaotic fiber lasers as transmitters and receivers, they achieved the concealment and demodulation of signals at a rate of 10 Mbit/s (Vanwiggeren et al. 1998).
