Hardware implementation of a neuron for neuromorphic optical system
Abstract
Specific features of neuromorphic systems construction and aspects of basic elements functions realisation are discussed. Hardware implementations of basic elements of pulsed neuromorphic optical system - synapses and neurones - based on the phase state change of thin-film structures made of chalcogenide materials under the influence of laser pulses are described. Calculations of optical characteristics of GeSbTe thin films in multilayer structures have been carried out. The hardware implementation of the main functions of optical neurons was analysed on the model with multilayer coatings based on phase-changeable materials.
