This is a book about the area of optical computing called photonic reservoir computing, which is an optical implementation of neural networks, a machine-learning technique.

The book has eight chapters, the first two being introductory chapters on this amazing optical-computation technique. Chapter 3 is about integrated on-chip reservoirs, and the subsequent chapters deal with various implementations of these computation techniques, including ones using semiconductor lasers.

The book is very clearly written by experts in the field and contains numerous experiments and references. It can be used by anyone working in optical computing, which has developed very much in recent years due to optical implementations of neural networks.
