非相干光反馈和非相干光注入下多重时延混沌激光二极管的同步

Synchronization in Multiple Time Delay Chaotic Laser Diodes Subject to Incoherent Optical Feedbacks and Incoherent Optical Injection

E. M. Shahverdiev, K. A. Shore

摘要:

首次报道了单向和双向耦合多时间延迟混沌激光二极管在非相干光反馈和非相干光注入下的同步机制。我们推导了存在条件,并数值研究了滞后,完全,预期同步制度和级联同步的稳定性。我们还详细研究了参数失配和噪声对同步质量的影响。它强调的是,敏感性的同步质量参数失配可能会导致高水平的安全性,由于难以复制的接收器激光。我们表明,从这个角度来看,注入电流和反馈延迟时间是非常重要的参数。

英文摘要:

We present the first report of the synchronization regimes in both unidirectionally and bidirectionally-coupled multiple time delay chaotic laser diodes subject to incoherent optical feedbacks and incoherent optical injection. We derive the existence conditions and numerically study the stability for lag, complete, and anticipating synchronization regimes and cascaded synchronization. We also study in detail the effect of parameter mismatches and noise on the synchronization quality. It is emphasized that sensitivity of the synchronization quality to parameter mismatches can lead to a high level of security due to the difficulty to replicate the receiver laser. We show that the injection current and feedback delay times are highly important parameters from this point of view.
