Opis

A pulse of light spreads in time as it propagates in a fiber due to the physical phenomenon called dispersion. While dispersion can be deleterious in optical communications systems, it can also be exploited to manage the temporal and spectral shapes of pulses and their interactions with other pulses. Much of dispersion control is realized in optical communications systems with discrete devices - the so-called dispersion compensators, and almost all commercially deployed dispersion compensators today are based on specially designed fibers. This book addresses various aspects of this device technology, such as the physics of optical dispersive effects, the design philosophy and properties of devices deployed in optical networks today, futuristic devices utilizing novel fibers, and their systems level impact. Written by leaders in the field drawn from both academia and industry, this book serves as a comprehensive introduction to the topic of dispersion management of light for graduate students and applications engineers. Since each chapter provides a detailed description of the state-of-the-art in each technological platform, this book also serves as a practical reference for industry experts tasked with designing next generation optical networks.

Dispersion management is a critical design criterion that characterizes the performance of an optical network, and has impacted almost every aspect of the physical layer of an optical transmission line. The past 10 years have seen an explosion in the variety of device effects exploited to obtain optimal performance from dispersion compensators, and this is the first book that deals exclusively with this technology. It starts with an exposition on the fundamental physics underlying dispersion and its effects on optical pulses, followed by at least one chapter devoted to each of the fiber-based dispersion-compensating devices that have either been deployed or are considered as serious candidates for future networks. The final section of this book then describes the systems-level impact of these devices, hence providing a one-stop reference for all aspects of optical-communication-network design pertaining to dispersion-management. Each chapter is written by the leading experts in the field, drawn from both academia as well as industry.
