Optical outer-product learning in a neural network using optically stimulable phosphor

Abstract

A novel application of optically stimulable phosphor (OSP) to a memory device for modifiable synaptic weights in a learnable optical neural network is experimentally demonstrated. OSP has many attractive features for mass storage of synaptic weight; it is analog, accessible in parallel, erasable and rewritable, high in resolution, and fast in response.
