Chaos based communication has been a very attractive research field from last couple of decades due to its potential of providing secure communication. In this paper, the authors reviewed principles and theory governing the field of chaos. They studied governing principles and different methods for chaotic signal generation and schemes used to modulate message signal with chaotic signal in optical fiber communication systems. They also reviewed the principal concepts governing chaos synchronization, types of chaos synchronization and some proposed techniques used for the synchronization of transmitter and receiver in optical fiber communication systems.
