First Demonstration of a Two-Layer All-Optical Neural Network by Using Photonic Integrated Chips and SOAs

Abstract

We demonstrate the first all-optical feed-forward neural networks constituted by two full photonic layers of neurons based on SOAs with Broadcast and Weighting protocol. The impact of optical nonlinear function is studied and signal processing with 10 Gbit/s binary sequences is presented which results in 0.21 error.
