Optoelectronic devices and fibre optics are the basis of cutting-edge communication systems. This monograph deals with the various components of these systems, including lasers, amplifiers, modulators, converters, filters, sensors, and more.
Advances in optical fibre based communications systems have played a crucial role in the development of the information highway. By offering a single mode oscillation and narrow spectral output, distributed feedback (DFB) semiconductor laser diodes offer excellent optical light sources as well as optical filters for fibre based communications and dense wavelength division multiplexing (DWDM) systems. This comprehensive text focuses on the basic working principles of DFB laser diodes and optical filters and details the development of a new technique for enhanced system performance. Considers the optical waveguiding characteristics and properties of semiconductor materials and the physics of DFB semiconductor lasers. Presents a powerful modelling technique based on the transfer matrix method which can be used to improve the design of laser diodes, optical fibres and amplifiers. Examines the effect of the various corrugation shapes on the coupling coefficients and lasing characteristics of DFB laser diodes. Technical advice to improve immunity against the spatial hole burning effect. Extensive referencing throughout and a comprehensive glossary of symbols and abbreviations. Suitable for both introductory and advanced levels This is an indispensable textbook for undergraduate and postgraduate students of electrical and electronic engineering and physics as it consolidates their knowledge in this rapidly growing field. As a technical guide for the structural design of DFB laser diodes and optical filters, the book will serve as an invaluable reference for researchers in opto-electronics, and semi conductor device physics.
The emergence of fibre optics as a commercially viable technology oc curred barely ten years ago; in this time it has become an established field with a variety of applications. This book has been written in an attempt to review the entire field with an emphasis on the practical applications of the technology. This approach has been adopted since it was felt that there was a need for a work which could be referred to by non -specialists in the field who were interested in, or who wished to make use of, fibre optics. With this readership in mind, the theory has been presented in as simple a manner as possible and emphasis has been placed on the description of typical applications and the manufacturing techniques of the technology. It is hoped that this mode of presentation will en able the reader to form an appreciation of both its advantages and its limitations.
Fiber Bragg gratings are flexible, cost-effective and highly efficient, with a vast range of potential applications. This timely new work provides a comprehensive description of the principles and practical applications of this latest technology, which has the potential to revolutionize telecommunications and significantly impact optical fiber sensing. Here the authors explain the underlying physics and practical aspects in a clear and unambiguous manner.
Volume 2 of TERB 3ed covers the convergence of telephony and data transport, including wireless networks. Now that data is becoming the predominant source of traffic more efficient multiplexing schemes and more flexible control methods are needed in the transport network, such as giving the customer the ability to call for bandwidth on demand. With the development of control methods for switched data services it is now recognised that improved ways to control the transport network are possible and standards initiatives are taking place to establish and improve the network control layer. Detailed explanation of propagation in wireless and optical fibre systems requires a substantial amount of mathematics, also covered in this volume. For each of the math chapters there is an explanation of why the mathematics is important, where it is applied and references to other chapters.
Since the invention of the laser, our fascination with the photon has led to one of the most dynamic and rapidly growing fields of technology. New advances in fiber optic devices, components, and materials make it more important than ever to stay current. Comprising chapters drawn from the author's highly anticipated book Photonics: Principles and Practices, Fiber Optics: Principles and Practices offers a detailed and focused treatment for anyone in need of authoritative information on this critical area underlying photonics. Using a consistent approach, the author leads you step-by-step through each topic. Each skillfully crafted chapter first explores the theoretical concepts of each topic, and then demonstrates how these principles apply to real-world applications by guiding you through experimental cases illuminated with numerous illustrations. The book works systematically through fiber optic cables, advanced fiber optic cables, light attenuation in optical components, fiber optic cable types and installations, fiber optic connectors, passive fiber optic devices, wavelength division multiplexing, optical amplifiers, optical receivers, opto-mechanical switches, and optical fiber communications. It also includes important chapters in fiber optic lighting, fiber optics testing, and laboratory safety. Containing several topics presented for the first time in book form, Fiber Optics: Principles and Practices is simply the most modern, detailed, and hands-on text in the field.
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.
Fibre Optics Is A Very Important Constituent Of Modern Information Technology. One Major Economic Benefit Offered By Fibre Optics Is Very High Information Transmission Rate At Low Cost Per Circuit-Km. The First Fibre Optic Telephone Link Went Public In Late 1970S. Ever Since, The Industrially Advanced Nations Around The World Have Been Striving To Deploy Fibre Optics In Almost Every Sector Of Communication Including Computer Networks And Data Links. Rarely, Since The Discovery Of Transistors, Have We Noticed Such A Fantastic Growth Rate Of A New Technology. As An Important Byproduct Of This Phenomenal Progress, A New Class Of Ultra-Sensitive Optical Sensors And Devices Based On Fibre Optics Has Emerged, Which Are Being Developed For Large Scale Use In Industrial And Biomedical Sectors. This Book Provides Semi-Tutorial Presentations Of The Fundamentals Of This Emerging Technology As Applied To Telecommunication And Sensor Development. Each Chapter, Contributed By Leading Researchers, Is Appended With A Large Number Of References To The Original Publications.The Book Is Broadly Divided Into Three Parts. The First Part Is Devoted To Propagation Effects In Optical Waveguides Including Polarization And Non-Linear Effects And Their Measurements. Fabrication And Cabling Technologies Of Optical Fibres Are Also Discussed In This Part.
