We experimentally report the cyclic scenario of birth and annihilation of periodic orbits in a photonic integrated circuit as the feedback phase of the electric field varies. The latter is also shown to result in minimal alterations in the statistical properties of the chaotic attractor, with simultaneously transiting the Hurst exponent H , erratically, below and above the critical value of H=0.5 that indicates regular Brownian motion. Consequently there is an indication of the most effective operating regions with minimized predictability, which hinders eavesdropping and the progress of forecasting the development of the chaotic light carrier.
我们通过实验报告了在光子集成电路中,随着电场反馈相位的变化,周期轨道的产生和湮灭的循环情况。结果还表明,这会导致混沌吸引子的统计特性发生最小程度的改变,同时使赫斯特指数H不稳定地在表明规则布朗运动的临界值H = 0.5上下转变。因此,存在可预测性最小的最有效工作区域的迹象,这阻碍了窃听以及对混沌光载波发展进行预测的进程。
