【Abstract】 Synchronization of chaotic lasing and its characteristics are studied on semiconductor lasers by injected to external light at 1.31 μm. This paper numerically researches the robustness of the synchronization system against mismatch of tye system parameters and additive white noise and chaotic secure communications with a 0.25 GHz sinusoidal signal by numerical simulation.The synchronous error is numerically calculated in the decoding process.Results prove that the systems have robust security and anti-uncover ability.更多还原
