In this paper,we propose and demonstrate experimentally and numerically a hierarchical time-delay optical reservoir computing(RC)system based on cascaded vertical-cavity surface-emitting lasers(VCSELs)with feedback and multiple injections.The prediction performance characteristics of the hier-archical time-delay RC system based on cascaded VCSELs under different reservoir layers are compared.Evidently,the prediction performance of the hierarchical time-delay RC system is first improved and sat-urates as the number of reservoir layers increases.Besides,the impacts of key factors on predicting the hierarchical time-delay RC system are also analyzed in detail experimentally and numerically.This proposed hierarchical time-delay RC system based on VCSELs is useful for the further development of RC systems and may be beneficial to improve the ability of RC systems to solve more complex problems.
