An Introduction To Fiber Optics

Textbook on the physical principles of optical fibers - for advanced undergraduates and graduates in physics or electrical engineering.

Introduction to Fiber-Optic Communications provides students with the most up-to-date, comprehensive coverage of modern optical fiber communications and applications, striking a fine balance between theory and practice that avoids excessive mathematics and derivations. Unlike other textbooks currently available, this book covers all of the important recent technologies and developments in the field, including electro-optic modulators, coherent optical systems, and silicon integrated photonic circuits. Filled with practical, relevant worked examples and exercise problems, the book presents complete coverage of the topics that optical and communications engineering students need to be successful. From principles of optical and optoelectronic components, to optical transmission system design, and from conventional optical fiber links, to more useful optical communication systems with advanced modulation formats and high-speed DSP, this book covers the necessities on the topic, even including today’s important application areas of passive optical networks, datacenters and optical interconnections. Covers fiber-optic communication system fundamentals, design rules and terminologies Provides students with an understanding of the physical principles and characteristics of passive and active fiber-optic components Teaches students how to perform fiber-optic system design, performance evaluation and troubleshooting Includes modern advances in modulation and decoding strategies

For courses in Introduction to Fiber Optics and Introduction to Optical Networking in departments of Electronics Technology and Electronics Engineering Technology. Also suitable for corporate training programs. Ideal for technicians, entry-level engineers, and other nonspecialists, this best-selling practical, thorough, and accessible introduction to fiber optics reflects the expertise of an author who has followed the field for over 25 years. Using a non-theoretical/non-mathematical approach, it explains the principles of optical fibers, describes components and how they work, explores the tools and techniques used to work with them and the devices used to connect fiber network, and concludes with applications showing how fibers are used in modern communication systems. It covers both existing systems and developing technology, so students can understand present systems and new developments.

This book explains physical principles, unique benefits, broad categories, implementation aspects, and performance criteria of distributed optical fiber sensors (DOFS). For each kind of sensor, the book highlights industrial applications, which range from oil and gas production to power line monitoring, plant and process engineering, environmental monitoring, industrial fire and leakage detection, and so on. The text also includes a discussion of such key areas as backscattering, launched power limitations, and receiver sensitivity, as well as a concise historical account of the field’s development.

A thorough account on the basics of fiber optics system design is contained in this volume. Introducing the topics from the vantage point of the student and professional electrical engineer, the aim of the text is to teach rather than merely present facts. The overall view of the text is toward practical engineering considerations including costs, and a discussion of radiation effects is associated with each appropriate chapter. The volume begins with a history of optical communications, leading to the now widely practiced field of fiber optics. Comparisons are made to conventional media and techniques: wire-line, coaxial cable, and radio. The nature and properties of optical fiber are examined, including manufacturing techniques, and fiber types and capabilities. The theory of light guidance is introduced in steps, beginning with a slab waveguide. Solutions of Maxwell's equations are derived and explained in view of the peculiar nature of the medium. Electro-optic devices are examined, including launching and detecting devices. The properties and varieties of these devices are explored. In particular, light-emitting diodes, injection laser diodes, p-i-n diodes, and avalanche photo diodes are covered. The electronic circuits necessary to adequately serve the electro-optic devices are examined and contrasted with more conventional types. Modulation techniques appropriate to optical fiber transmission systems are enumerated and compared. Overall system considerations are addressed, and examples are given of various systems that have been deployed, or are planned for deployment. Expectations for future developments and trends in the field are enumerated, with indications of their significance. Topics such as ultra-low-loss fiber and coherent detections techniques are discussed. Appendices comprising an accounting of useful laboratory equipment, mathematical relations employed in the body of the text, and complete exercise solutions are included.

Introduction to Fiber Optics is well established as an introductory text for engineers, managers and students. It meets the needs of systems designers, installation engineers, electronic engineers and anyone else looking to gain a working knowledge of fiber optics with a minimum of maths. Review questions are included in the text to enable the reader to check their understanding as they work through the book. The new edition of this successful book is now fully up to date with the new standards, latest technological developments and includes a new chapter on specifying optical components. Whether you are looking for a complete self-study course in fiber optics, a concise reference text to dip into, or a readable introduction to this fast moving technology, this book has the solution. * A practical, no-nonsense guide to fiber optics * Up-to-date coverage that minimises mathematics * New material on specifying optical components

The authors deliver a complete overview of fiber-optic Fabry-Perot (FFP) sensing technology, integrating the knowledge and tools of multiple fields including optics, sensing, micromachining, instrumentation, physics, and materials science. The main chapters discuss operating principles, microstructures, fabrication methods, signal demodulation, and instrumentation. This treatment spans the full range of structures (intrinsic/extrinsic, multimode fiber vs single-mode fibers), as well as advanced micromachining technologies and major interrogating and multiplexing methods for the formation of multi-point, quasi-distributed sensing networks. Readers will also gain a summary of state-of-the-art applications in oil, gas, and electricity industries, aerospace technology, and biomedicine.

This book tells you all you want to know about optical fibers: Their structure, their light-guiding mechanism, their material and manufacture, their use. It began with telephone, then came telefax and email. Today we use search engines, music downloads and internet videos, all of which require shuffling of bits and bytes by the zillions. The key to all this is the conduit: the line which is designed to carry massive amounts of data at breakneck speed. In their data carrying capacity optical fiber lines beat all other technologies (copper cable, microwave beacons, satellite links) hands down, at least in the long haul; wireless devices rely on fibers, too. Several effects tend to degrade the signal as it travels down the fiber: they are spelled out in detail. Nonlinear processes are given due consideration for a twofold reason: On the one hand they are fundamentally different from the more familiar processes in electrical cable. On the other hand, they form the basis of particularly interesting and innovative applications, provided they are understood well enough. A case in point is the use of so-called solitons, i.e. special pulses of light which have the wonderful property of being able to heal after perturbation. The book will take you from the physical basics of ray and beam optics, explain fiber structure and the functions of optical elements, and bring you to the forefront of both applications and research. The state of the art of high speed data transmission is described, and the use of fiber optic sensors in metrology is treated. The book is written in a pedagogical style so that students of both physics and electrical engineering, as well as technicians and engineers involved in optical technologies, will benefit. The new edition is largely updated and has new sections on nonlinear phenomena in fibers as well as on the latest trends in applications.
