RGB Color-Discriminable Photonic Synapse for Neuromorphic Vision System

Abstract

Highlights Photonic synapse capable of multispectral color discrimination is demonstrated. Strong excited-state dipoles enable remarkable discrimination intensity (0.05–40 mW cm-2). This approach is not restricted to a specific medium in the channel layer, and convolutional neural network with synapses array achieves over 94% inference accuracy for Canadian-Institute-For-Advanced-Research-10 images.
