Within the past few decades, information technologies have been evolving at a tremendous rate, causing profound changes to
our world and our ways of life. In particular, fiber optics has been playing an increasingly crucial role within the telecommunication
revolution. Not only most long-distance links are fiber based, but optical fibers are increasingly approaching the individual
end users, providing wide bandwidth links to support all kinds of data-intensive applications such as video, voice, and data
services. As an engineering discipline, fiber optics is both fascinating and challenging. Fiber optics is an area that incorporates
elements from a wide range of techno- gies including optics, microelectronics, quantum electronics, semiconductors, and networking.
As a result of rapid changes in almost all of these areas, fiber optics is a fast evolving field. Therefore, the need for
up-to-date texts that address this growing field from an interdisciplinary perspective persists. This book presents an overview
of fiber optics from a practical, engineering perspective. Therefore, in addition to topics such as lasers, detectors, and
optical fibers, several topics related to electronic circuits that generate, detect, and process the optical signals are covered.
In other words, this book attempts to present fiber optics not so much in terms of a field of "optics" but more from the perspective
of an engineering field within "optoelectronics.
