提出了一种宽带混沌网络，并研究了其混沌同步性能。结果表明，利用来自驱动垂直腔面发射激光器(D-VCSEL)的带宽增强型混沌信号(带宽约为42 GHz)驱动宽带混沌网络中的所有响应型垂直腔面发射激光器(R-VCSEL)，在最佳注入参数下，可以实现任意两个R-VCSEL中线偏振(LP)模之间带宽超过30 GHz的高质量混沌同步，且D-VCSEL与R-VCSEL之间的相关系数较低。以两个LP模式作为两个不同的通信通道，该混沌网络有可能实现基于几GHz弛豫振荡频率的VCSEL的60 GHz以上的大容量保密通信。
A broadband chaos network is proposed and its chaos synchronization performance is investigated. The results show that, using a bandwidth-enhanced chaotic signal (about 42GHz bandwidth) from a drive vertical-cavity surface-emitting laser (D-VCSEL) to drive all response VCESLs (R-VCSELs) in the broadband chaos network, high-quality chaos synchronization with over 30GHz bandwidth between two corresponding linear polarization (LP) modes in arbitrary two R-VCSELs can be obtained under optimum injection parameters, while the correlated coefficients between the D-VCSEL and R-VCSELs are low. Taking two LP modes as two different communication channels, this chaos network may possess the potentiality to realize more than 60GHz high-capacity secret communication based on VCSELs with several GHz of relaxation oscillation frequency.
