Chaos Theory is known to have a broad range of applications in science and engineering, and is now also contributing insights to various other fields such as the social sciences and management.

In particular in the interdisciplinary field of secure communications there has been a great deal of interest in chaos-based encryption in the last two decades, essentially due to its inherent security features, and its both easy and low-cost implementation schemes. E.g. it has been recognized that the rich phenomenon of chaos synchronization can be readily used as a cryptosystem for digital and analog communications. Very recently projective synchronization has been investigated for faster communications - in such a scheme, the constant transformation of the driving and response variables with their scaling factor can be applied to extend a binary digital signal to m-nary digital signals so as to make communication significantly faster.

Meanwhile, chaos-based optical communications have also become a prime field of interest due to their rapid theoretical development as well as their related experimental implementations. For example semiconductor lasers, which are naturally chaotic and can be synchronized by suitably tuning the input parameters, have proven to be useful as communication transceivers.

Presently, cluster and full synchronizations in optical networks are also being investigated for the dynamics of communications at each node. Here, star and ring-type structures are two well known and stable topologies for optical network communications.
