论文摘要
我们使用统计工具来表征可激发系统对周期性扰动的响应。该系统是在注射场相的脉冲扰动下进行光学注射的半导体激光器。我们通过计算激光器在$δ$ t的时间间隔内计算激光响应的表征，该脉冲数$δ$ t在应用扰动时开始。然后将成功率SR（$δ$ t）定义为相对于扰动的数量，在间隔$δ$ t中发出的脉冲数。用$δ$ t对SR变化的分析允许分离技术来源的恒定滞后和物理和动态起源的频率依赖性滞后。一旦考虑到滞后，成功率清楚地捕获了锁定和解锁政权及其之间的过渡。我们预计，成功率将是分析定期强制系统输出的实用工具，尤其是在需要通过小型周期性扰动生成非常规定的振荡时。
We use statistical tools to characterize the response of an excitable system to periodic perturbations. The system is an optically injected semiconductor laser under pulsed perturbations of the phase of the injected field. We characterize the laser response by counting the number of pulses emitted by the laser, within a time interval, $Δ$T , that starts when a perturbation is applied. The success rate, SR($Δ$T), is then defined as the number of pulses emitted in the interval $Δ$T , relative to the number of perturbations. The analysis of the variation of SR with $Δ$T allows to separate a constant lag of technical origin and a frequency-dependent lag of physical and dynamical origin. Once the lag is accounted for, the success rate clearly captures locked and unlocked regimes and the transitions between them. We anticipate that the success rate will be a practical tool for analyzing the output of periodically forced systems, particularly when very regular oscillations need to be generated via small periodic perturbations.
