Abstract
An optical-readout synaptic device based on SiONand a preparation method thereof are provided. The device includes a surface plasmonic waveguide and a memristor; the surface plasmonic waveguide has a vertical three-layer structure that a second metal layer, a SiNdielectric layer and a first metal layer are successively arranged from top to bottom; the memristor has a vertical four-layer structure that a second electrode layer, a second resistive layer, a first resistive layer and a first electrode layer are successively arranged from top to bottom; the memristor is embedded in the surface plasmonic waveguide; and, the first resistive layer and the second resistive layer of the memristor serve as an optical signal transmission channel that is horizontally connected with the SiNdielectric layer of the surface plasmonic waveguide. The present invention realizes an optical-readout of synaptic weight and has incomparable advantages over a conventional electrical-readout synaptic device.
