Abstract

In order to supply a theoretical guide for chaotic telecommunication, the influences of the chromatic dispersion and nonlinearity in fiber on the chaotic synchronization have been investigated based on the theoretical models used to describe the dynamics of semiconductor laser subjected to the external optical feedback and signal transmission in fiber channel. The numerical simulation results show that, the fiber nonlinear effect is responsible for the phase varying of chaotic signal and do not affect the amplitude of the chaotic signal; due to chromatic dispersion, the amplitude characteristics of chaotic signal are distorted significantly and the system synchronization quality will be impaired; after propagating 200km in dispersion shifted fiber, a desirable system chaotic synchronization with a synchronized coefficient 0.99 can be achieved by adopting a amplifier before the received laser to compensate the fiber loss.
