Temporal summation in a neuromimetic micropillar laser
Résumé
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 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.
