光注入半导体激光器中的积累层和周期叠加
Accumulation horizons and period-adding in optically injected semiconductor lasers
摘要：
研究了光注入单模半导体激光器相图中混沌区域内稳定周期振荡岛的分级结构。相图显示出显著的{ \it积累层}：由不断增加的周期解的自相似岛的无限级联积累形成的边界。每个级联都遵循特定的期间添加路由。通过这种周期性解的网络对混沌激光相位的筛选可能会损害利用混沌信号操作的应用，例如安全通信。
英文摘要：
We study the hierarchical structuring of islands of stable periodic oscillations inside chaotic regions in phase diagrams of single-mode semiconductor lasers with optical injection. Phase diagrams display remarkable {\it accumulation horizons}: boundaries formed by the accumulation of infinite cascades of self-similar islands of periodic solutions of ever-increasing period. Each cascade follows a specific period-adding route. The riddling of chaotic laser phases by such networks of periodic solutions may compromise applications operating with chaotic signals such as e.g. secure communications.
