Neuromimetic systems are systems mimicking the functionalities or architecture of biological neurons and may present an alternative path for efficient computing and information processing. We demonstrate here experimentally temporal summation in a neuromimetic micropillar laser with an integrated saturable absorber. Temporal summation is the property of neurons to integrate delayed input stimuli and to respond by an all-or-none kind of response if the inputs arrive in a sufficiently small time window. Our system alone may act as a fast optical coincidence detector and paves the way to fast photonic spike-processing networks.
神经拟态系统是模仿生物神经元功能或架构的系统，可能为高效计算和信息处理提供一条替代途径。我们在此通过实验证明了在具有集成可饱和吸收体的神经拟态微柱激光器中存在时间总和现象。时间总和是神经元的一种特性，即整合延迟的输入刺激，并在输入在足够小的时间窗口内到达时以全或无的方式做出响应。仅我们的系统就可以充当快速光学符合探测器，并为快速光子尖峰处理网络铺平道路。
