Abstract :This paper numerically investigates the synchronization and the chaos-based encryption using unidirectional coupled chaotic semiconductor ring lasers insert ignore into journalissuearticles values(SRLs); with direct modulation. A good quality of synchronization and transmission of messages are realized for specific choice of system parameters. The mismatches of typical internal SRLs parameters have an influence on the quality of synchronization. While the communication performance of the system has a good robustness to the mismatches of typical internal SRLs parameters. Finally, the encrypted message can be recorvered without using any filter.
