论文摘要
我们通过实验表明，基于耦合的退化参数振荡器的相同光子尖峰神经元的网络可以显示各种嵌合体状态，其中，根据其局部同步和去同步，不同种类的尖峰动态可以以自组织的方式发展。即使仅实现了静态相互作用，通过来自连接的神经元的同步输入，光子神经元的尖峰模式也可以自发地和自适应地在A. L. Hodgkin分类的I类和II类模式之间进行自适应变化。尽管所有神经元具有相同的自然尖峰频率，但这种自发的尖峰模式移动仍会引起峰值频率的显着变化，这鼓励了嵌合体的产生。当前系统中尖峰模式的可控性和自组织的灵活性使我们能够创建一个实验平台，以探索神经形态尖峰神经网络中嵌合体状态的性质。
We experimentally demonstrate that networks of identical photonic spiking neurons based on coupled degenerate parametric oscillators can show various chimera states, in which, depending on their local synchronization and desynchronization, different kinds of spiking dynamics can develop in a self-organized manner. Even when only a static interaction is implemented, through synchronized inputs from connected neurons, the spiking mode of photonic neurons can be spontaneously and adaptively changed between the Class-I and Class-II modes classified by A. L. Hodgkin. This spontaneous spiking-mode shift induces a significant change in the spiking frequency despite the all neurons having the same natural spiking frequency, which encourages the generation of chimera states. Controllability and self-organized flexibility of the spiking modes in the present system allow us to create an experimental platform to explore the nature of chimera states in neuromorphic spiking neural networks.
