This book describes both the theoretical and experimental aspects of optical soliton generation, soliton properties and the application of optical solitons to all-optical high-bit-rate communications. Only temporal optical solitons in fibres are considered. The intention of the book is to provide an overview of our current understanding of optical soliton properties, introducing the subject for the student and reviewing the most recent research. Each chapter has been written by experts, indeed chapters 1 and 2 have been contributed by the pioneers of theoretical and experimental optical soliton research Dr A. Hasegawa and Dr L. F. Mollenauer respectively. The book will be of importance to graduate students and researchers in optics, optical engineering and communications science, providing a useful introduction for those who are entering the field. It will provide an up-to-date summary of recent research for the expert, who will also find the references to each chapter extremely valuable.
