基于相互耦合的半导体激光器（代表星型和网状网络）的两种多半导体激光器（SL）拓扑，根据其同步潜力及其对关键 SL 内在和操作参数的敏感性进行评估。耦合拓扑、耦合条件和关键 SL 参数的值决定了发射光信号的动态类型。节点的数量及其基本属性的失谐已被评估为对于同步输出的效率和质量以及网络的整体动态图具有决定性作用。我们的研究主要集中在 SL 参数值的差异及其对同步动态效率的影响。此类研究将为在各种耦合矩阵下构建实验性大规模耦合 SL 网络提供初步指导，以支持光学传感或加密应用。
Two multi-semiconductor-laser (SL) topologies, based on mutually coupled semiconductor lasers - representing a startype and a mesh-type network - are evaluated in terms of their synchrony potential and their sensitivity towards critical SLs' intrinsic and operational parameters. The coupling topology, the coupling conditions and the values of key SL parameters determine the type of dynamics of the emitted optical signals. The number of nodes and the detuning in their fundamental properties have been assessed to be decisive in terms of efficiency and quality of synchronized outputs, as wells as for the overall dynamical map of the network. Our investigation mainly focuses on discrepancies in SL parameter values and their effect on the efficiency of synchronized dynamics. This type of investigation will provide preliminary guidelines on building experimentally large scale networks of coupled SLs under various coupling matrices that could support optical sensing or cryptographic applications.
