Temporal summation in a neuromimetic micropillar laser

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.
