Photonic Reservoir Computing: Exploiting Complex Photonics for Information Processing

Abstract

Reservoir computing (RC), which is a computational paradigm that uses dynamical systems, is a powerful tool for solving highly complex and abstract computational tasks. RC has recently been implemented in a variety of physical systems, including photonic systems. This article introduces its fundamental concepts and recent advances in its optical implementation. As relevant topics, optical implementations of extreme learning machine and deep learning are also discussed.
