摘　　要：利用一个带有光反馈和光注入的光泵浦自旋垂直腔表面发射激光器的两个混沌偏振分量形成两个并行储备池计算机。这些储备池用来学习另外一个光泵浦自旋垂直腔表面发射激光器(发射激光器)混沌动力学行为。训练基于自旋垂直腔表面发射激光器的储备池获得一个发射的偏振分量和它相应的训练储备池之间的高质量混沌同步。在这种高质量同步条件以及确保安全性前提下,实现了16QAM信息的双信道保密通信。此外,针对两个解密信息,进一步讨论在不同参数下它们的误码率。结果表明,不同参数改变下的误码率率均为0。研究结果表明,时延光学混沌储备池计算为光学混沌保密通信的实际应用提供了一种有效的方法。Optically pumped spin-polarized vertical-cavity surface-emitting lasers might provide properties superior to electrically pumped vertical-cavity surface-emitting lasers,such as faster modulation dynamics,lager modulation bandwidth,lower threshold,and stronger polarization determination. New applications of optically pumped spin-vertical-cavity surface-emitting lasers are foreseen in high-speed optical communication, optical information processing, data storage, quantum computing and biochemical sensing. Various forms of ultrafast instability are observed in optically pumped spin-vertical-cavity surfaceemitting lasers,including periodic oscillations,polarization switching,and chaos dynamics. Due to weak material and cavity anisotropy,the output of electrically pumped vertical-cavity surface-emitting laser usually includes two orthogonal polarization components,which is beneficial to realize dual channel optical communication. Therefore,the dual-channel secure communications based on electrically pumped verticalcavity surface-emitting lasers have received extensive attention in recent years. In most of these examples,the drive-response electrically-pumped vertical-cavity surface-emitting lasers system was always used for secure communications. In such a system,chaotic x-polarization component and y-polarization component were yielded via the introduction of the external perturbations,typically feedback in the drive verticalcavity surface-emitting laser. The response vertical-cavity surface-emitting laser yielded similar chaotic xpolarization component and y-polarization component when its parameters were identical to those of the drive vertical-cavity surface-emitting laser. Moreover, chaos synchronization between each pair of polarization components played a key role in security and encrypted message recovery. However,the realization of high-quality chaos synchronizations relies on the assumptions that the drive and response electrically pumped vertical-cavity surface-emitting lasers are completely symmetrical in
