【Abstract】 Optical fiber plays an important role in the high-speed wired communication because of its outstanding properties,such as high bandwidth,large capacity and low interference,etc.Recently,chaos-based communication methods have become a research focus in the area of optical fiber communication due to the development of nonlinear chaotic theory.The motivation lies in the advantages provided by the chaotic signal.In this paper,several communication schemes and test results are given for the design of chaotic optical communication systems with generation of chaotic optical source,chaotic synchronization methods and chaotic encryption considered.On this basis,the characteristics and application scopes of existing methods are analyzed and the future research direction on the chaotic optical communication is pointed out.更多还原
