提出了一种基于非相干光反馈半导体激光器的双向混沌通信系统,数值研究了该系统的同步特性及通信性能.结果表明,当两个激光器参数一致时,系统能获得无延时的高质量混沌同步,实现实时双向通信;当激光器内部参数失配时,系统的同步性能及通信质量会受到一定的影响,但该系统对参数失配的容忍性较好,在一定的参数失配范围内,系统仍能实现较好的双向混沌通信.
A bi-directional chaotic communication system based on incoherent optical feedback semiconductor laser is proposed, and its synchronization and communication performance are numerically studied. The results show that the system can obtain high quality chaos without delay when the two laser parameters are consistent Synchronization and real-time bidirectional communication. When the internal parameters of the laser are mismatched, the synchronization performance and communication quality of the system will be affected to a certain extent. However, the tolerance of the system to parameter mismatch is good. Within a certain parameter mismatch, The system can still achieve better two-way chaotic communication.
