摘　　要：结合时延储备池计算和垂直腔面发射激光器,基于现有的光纤光学平台,对以1550 nm波段垂直腔面发射激光器为非线性节点的时延光储备池计算系统进行了实验研究。结果表明,在该实验系统中可以分别成功地实现单个Santa-Fe混沌时间序列预测任务以及单个非线性信道均衡任务。基于垂直腔面发射激光器在特定参数条件下能实现双模共存,进一步在该系统中垂直腔面发射激光器的两个偏振模式中同时注入外部信号,成功地完成了Santa-Fe混沌时间序列预测和非线性信道均衡任务的并行处理,但是整体性能要弱于单任务处理性能;除此之外,并行任务的性能随着外光注入强度的增加而得到改善,其中注入强度比率大的一方性能更好。Combined with the time delay reservoir computing and vertical cavity surface emitting laser,based on the existing fiber optic platform,an experimental study on the time delay reservoir computing system with the 1550 nm waveband vertical cavity surface emitting laser as the nonlinear node is carried out.The results show that a Santa-Fe chaotic time series prediction task and a single nonlinear channel equalization task can be successfully implemented in the experimental system.Based on the vertical cavity surface emitting laser that can achieve two polarization modes coexistence under certain parameter conditions,external signals are further injected into the two polarization modes of vertical cavity surface emitting laser simultaneously,and the parallel processing of Santa Fe chaotic time series prediction and signal nonlinear trace equalization is successfully completed,however,the performance of parallel tasks processing is weaker than the performance of single task processing.Besides,the performance of the parallel task processing is improved with the increase of the external light injection intensity,and the performance of the side with the larger injection intensity ratio is better.
