Bubbling in delay-coupled lasers

V. Flunkert, O. D'Huys, J. Danckaert, I. Fischer, E. Schoell

摘要:

从理论上研究了通过有源或无源中继延迟耦合的两台激光器的混沌同步。虽然激光器是同步的,但它们的动态特性与无源继电器的具有延迟反馈的单个激光器相同,并且与有源继电器的两个延迟耦合激光器相同。取决于耦合参数,系统表现出起泡,即,噪声引起的去极化或开关不极化。我们关联的相干崩溃和低频波动制度的横向不稳定性的一些复合腔的反模的去相干化动力学。最后,我们演示了如何,通过使用一个积极的继电器,冒泡可以抑制。

英文摘要:

We theoretically study chaos synchronization of two lasers which are delay-coupled via an active or a passive relay. While the lasers are synchronized, their dynamics is identical to a single laser with delayed feedback for a passive relay and identical to two delay-coupled lasers for an active relay. Depending on the coupling parameters the system exhibits bubbling, i.e., noise-induced desynchronization, or on-off intermittency. We associate the desynchronization dynamics in the coherence collapse and low frequency fluctuation regimes with the transverse instability of some of the compound cavity's antimodes. Finally, we demonstrate how, by using an active relay, bubbling can be suppressed.
