论文摘要
反馈延迟的兴奋系统在从生物学到神经科学和光学的领域中很重要。它们维持了多种脉冲制度，在反馈循环中具有不同数量的等距脉冲。从实验和理论上，我们报告了光学系统中这些方案的脉搏观察对称性破坏。分叉分析揭示了这起源于共振现象，而对称性态在参数空间的大区域中是稳定的。这些结果对例如光子学有影响。光脉冲的光学计算和多功能源。
Excitable systems with delayed feedback are important in areas from biology to neuroscience and optics. They sustain multistable pulsing regimes with different number of equidistant pulses in the feedback loop. Experimentally and theoretically, we report on the pulse-timing symmetry breaking of these regimes in an optical system. A bifurcation analysis unveils that this originates in a resonance phenomenon and that symmetry-broken states are stable in large regions of the parameter space. These results have impact in photonics for e.g. optical computing and versatile sources of optical pulses.
