*Provides the reader with insight and understanding for key active optical components frequently being / to be used in the optical communication systems, essential building blocks of today's/next generation fiber optic networks*Allows engineers working in optical communication area, (from system to component) to understand the principle and mechanics of each key component they deal with for optical system design*Covers different laser diodes as transmitter and pumping sources, different modulators, and different photodetectorsWDM Technologies: Active Optical Components along with the companion title WDM Technolgies: Passive Optical Components form the first set of books which cover all key active optical components required for current and next generation optical communication systems. World-renowned authors, who are pioneers in their research area, have written the chapters in their area of expertise. The book highlights not only the principle of operation and characteristics of the active optical components, but also provide an in-depth account of the state-of-the-art fabrication technology, and packaging technology for commercial modules. In addition the book helps you to choose the right device for a given system application and highlights operating principle of each component, fabrication technologies, and packaging/module technologies.This book will be an excellent resource for engineers and researchers engaged in all aspects of fiber optics communication, such as, optoelectronics, equipment/system design, and manufacturing. The book is also a resource for graduate students and scholars interested in these rapidly growing fields.
