We report the first demonstration of excitability in an all-fiber laser. We present clear experimental evidence in this passively $Q$-switched device with gain and absorber sections for defining properties of excitability, including a threshold-based excitable response and a decreasing reaction delay between input pulse and excitatory response with increasing perturbation amplitude. Our experimental results are consistent with the homoclinic/saddle-loop mechanism that forms the basis of excitability as demonstrated by a study of the Yamada model; they pave the way toward novel and reliable all-fiber architectures for neuro-inspired photonic memory and computing applications.

具有饱和吸收器部分的全光纤激光器的激发性

我们报告了在全光纤激光器中激发性的首次演示。我们在这种带有增益和吸收器部分的无源$ Q $开关设备中提供了明确的实验证据，这些设备用于定义兴奋性，包括基于阈值的兴奋性响应以及随着摄动幅度的增加，输入脉冲与兴奋性响应之间的反应延迟减小。我们的实验结果与基于Yamada模型的研究所证明的构成兴奋性基础的同斜/鞍环机制是一致的。他们为面向神经启发的光子存储和计算应用的新型，可靠的全光纤架构铺平了道路。
