摘　　要：提出了基于光电反馈的激光混沌并联同步方案,对可能存在的两种同步——广义同步和完全同步进行了研究,着重讨论了激光器内部参数失配对发射与接收激光器之间以及并联接收激光器之间同步特性的影响.研究结果显示:在一定范围内,同样的内部参数失配下,并联接收激光器之间的同步效果明显优于发射激光器与接收激光器之间的同步效果.A chaotic parallel synchronization model of optoelectronic feedback semiconductor lasers is proposed. The complete synchronization and generalized synchronization are studied,while the effect of intrinsic parameter mismatch on the difference in the synchronization performances between the drive laser and receive laser or between the parallel receive lasers is emphatically discussed. The results show that zero-time-lag complete synchronization between the drive laser and parallel receive laser can be realised under parameter match. For generalized synchronization,if one of the intrinsic parameters of the receive laser is changed,the cross correlation between the parallel receive lasers is larger than that between the drive laser and the receive laser over a wide parameter mismatch range.
