Optoelectronic spiking neuron that is based on bispin-device is described. The neuron has separate optical inputs for excitatory and inhibitory signals, which are represented with pulses of single polarity. Experimental data, which demonstrates similarity in form of output pulses and set of functions of the suggested neuron and a biological one is given. An example of hardware implementation of optoelectronic pulsed neural network (PNN) that is based on proposed neurons is described. Main elements of the neural network are a line of pulsed neurons and a connection array, part of which is made as a spatial light modulator (SLM) with memory. Usage of SLM allows modification of weights of connections in the learning process of the network. It is possible to create adaptive (capable of additional learning and relearning) optoelectronic PNNs with about 2000 neurons. [ABSTRACT FROM AUTHOR] |
