Abstract
A processing device comprises a plurality of artificial neurons comprising first and second artificial neurons, at least one optical connection between an optical output of the first artificial neuron and an optical input of the second artificial neuron, the optical input comprising a photosensitive element, at least one weighting element connected to the optical input of the second artificial neuron, configured to modify a gain of the optical input of the second artificial neuron, and at least one nonlinear element having an input and connected to the optical output of the first artificial neuron, configured to activate the optical output when a signal received at the input of the at least one nonlinear element rises above a threshold, wherein the optical output of the first artificial neuron comprises at least one thin film light-generating component. An LED neuron is also described.
