Fast prototype of the optical broadcast interconnection neural network architecture

This paper reports the recent steps to the attainment of a compact high-speed optoelectronic neuroprocessor based on an optical broadcast architecture. The optical broadcast architecture is composed of a set of electronic processing elements that work in parallel and whose input is introduced by means of an optical sequential broadcast interconnection. Because of the special characteristics of the architecture, that exploits electronics for computing and optics for communicating, it is readily scalable in number of neurons and speed. This paper focuses on the improvement of the optoelectronic system and electronic neuron design to increase operation speed with respect to previous prototype.
