Neuromimetic systems are systems mimicking the functionalities orarchitecture of biological neurons and may present an alternativepath for efficient computing and information processing. We demonstratehere experimentally temporal summation in a neuromimetic micropillarlaser with integrated saturable absorber. Temporal summation is theproperty of neurons to integrate delayed input stimuli and to respondby an all-or-none kind of response if the inputs arrive in a sufficientlysmall time window. Our system alone may act as a fast optical coincidence detector and paves the way to fast photonic spike processing networks.
