数值研究了具有非均匀延迟的互耦合半导体激光器全光星星网络中广义滞后同步（GLS）的同步特性和灵敏度。中心节点和侧节点以不对称的注入强度光学耦合。研究了激光器的泵浦电流、注入强度、非对称注入因子和频率失谐分布对GLS的影响。研究发现，在非均匀时延的星星网络中，除了注入强度和频率失谐外，中心激光器的泵浦电流和非对称注入因子也是决定GLS质量的关键因素。为了获得宽参数范围内的高质量GLS，建议采用极不对称注入和大泵浦电流的中心激光器。这种GLS也可以在具有异质耦合时延的大规模激光网络中获得，并且几乎不受时延分布的影响，这为边节点之间的多用户混沌通信和基于同步的安全密钥分发网络提供了可能。
The synchronization properties and the sensitivity of generalized lag synchronization (GLS) in all-optical star network with mutually coupled semiconductor laser in the presence of heterogeneous delays are investigated numerically. The hub node and the side nodes are optically coupled with asymmetrical injection strength. The dependence of GLS on the effects of lasers' pump current, injection strength, asymmetrical injection factor, and frequency detuning distribution is examined. It is found that, except for the injection strength and frequency detuning, the pump current of hub laser and the asymmetrical injection factor are also key factors that determine the quality of GLS in star network with heterogeneous delays. Extremely asymmetrical injection as well as large pump current of hub laser is suggested to obtain high-quality GLS in wide parameter regions. Such GLS can also be obtained in a large-scale laser network with heterogeneous coupling delays, and is hardly affected by the time delay distribution, which opens possibilities for multi-user chaotic communication and synchronization-based secure key distribution network among the side nodes.
