  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.
