【 摘 要 】

Synchronization between two Rössler circuits coupled with semiconductor laser for satisfies secure communication was presented. The two circuits are synchronized via one variable dynamic electronic channel, while and the external signal is transmitted by another variable dynamic through an optical fiber. This system exhibit more fixity and flexibility. Experimentally and numerically results are studied by changing the bidirectional coupling factor. The sinusoidal signal was used in secure communications. The results of numerical simulation are excellent agreement with experiment which demonstrate that the system is viable.
