An array of photodetectors, each having a variable sensitivity, forms the most important component of our two gallium arsenide chips. We designed the optical neurochip so that variable sensitivity photodiodes are monolithically integrated on top of an LED array, serving both as fast analog multipliers and as on-chip weight storage elements with learning capability. Our artificial retina device combines a VSPD array with a neural network for postprocessing, allowing us to perform fast, yet flexible, processing operations on projected images.<>
