Fundamentals of Optical Fiber Sensor Technology The field of optical fiber sensors continues to expand and develop, being increasingly influenced by new applications of the technologies that have been the topics of research for some years. In this way, the subject continues to mature and reach into new areas of engineering. This text in the series on Optical Fiber Sensor Technology provides a foundation for a better understanding of those developments in the basic science and its applications in fiber sensors, underpinning the subject today. This book builds upon the work in an earlier single volume which covered a broad area of the subject, but which now, in this, volume 1 of the series, focuses upon the fundamentals and essentials of the technology. Material which is included has been carefully reviewed and in most cases thoroughly revised and expanded to reflect the current state of the subject, and provide an essential background for the more applications-oriented content of the subsequent volumes of the series. This volume opens with a status paper on optical fiber sensor technology, by Kenneth Grattan and Tong Sun providing in it a flavor of the main topics in the field and giving an essential overview at the sort of systems which are discussed in more detail in the other chapters in the whole series. An extensive publication list of readily accessible papers reflecting these topics is included.

This is a concise introduction into optical fiber communication.

Fundamentals of Optical Fibers offers students a timely, pedagogically consistent introduction to the fundamental principles of light propagation in fibers. In it, Professor John A. Buck reviews, in depth, fundamental waveguiding concepts, the influence of various fiber structures and materials on light transmission, nonlinear light propagation effects occurring in fibers, and various measurement techniques. Since the chief application of optical fibers is in communication systems, throughout the book the focus is on topics which pertain to that domain. In the first part of the text, the author lays the groundwork for later discussions with a detailed review of the relevant electromagnetic principles and how they apply to the analysis of wave propagation. He also introduces basic field equations and delineates the fundamental principles of dielectric waveguides. In the second part, he explores the limitations of fiber transmission, paying particular attention to the problems of loss and dispersion. He reviews fabrication procedures and alternative fiber designs as they relate to minimizing loss and dispersion. And he presents field analysis methods for single mode and multimode fibers having graded index profiles. In the last part, Professor Buck reviews the basics of nonlinear optics and discusses the origins of nonlinear effects and the conditions under which they appear in fibers. This section also features a discussion of fiber amplifiers, along with a review of the fundamentals of light amplification by stimulated emission. Offering a well-balanced presentation of the basics of light propagation in fibers, and including real-world examples and end-of-chapter problems, Fundamentalsof Optical Fibers is an excellent text for senior- to graduate-level courses in electrical engineering or physics. It is accessible to anyone who has taken at least a one-semester course in electromagnetics at the undergraduate level.

Environmental and chemical sensors in optical fiber sensor technology The nature of the environment in which we live and work, and the precarious state of many aspects of the natural environment, has been a major lesson for scientists over the last few decades. Public awareness of the issues involved is high, and often coupled with a scepticism of the ability of the scientist and engineer to provide an adequate, or even rapid solution to the preservation of the environment before further damage is done, and to achieve this with a mini mum of expenditure. Monitoring of the various aspects of the environment, whether it be external or internal to ourselves and involving chemical, physical or biomedical parameters is an essential process for the well-being of mankind and of the individual. Legis lative requirements set new standards for measurement and control all around us, which must be met by the most appropriate of the technologies available, commensurate with the costs involved. Optical fiber sensor technology has a major part to play in this process, both to complement existing technologies and to promote new solutions to difficult measurement issues. The developments in new sources and detectors covering wider ranges of the electromagnetic spectrum, with higher sensitivity, allow the use of techniques that some time ago would have been considered inappropriate or lacking in sufficient sensitivity."

Bidirectional transmission over optical fibre networks may yield a large cost reduction because of the reduction of the network infrastructure by a factor two and the potential cost reduction by an integrated transceiver design. It may also provide a cost-effective way to upgrade distribution networks by adding bidirectional channels. This book is the first to provide a comprehensive overview of bidirectional transmission in optical networks. It handles physical aspects: the behaviour of the fibre itself in bidirectional transmission transmission aspects: the behaviour and design of bidirectional systems and network aspects: the influence of bidirectional transmission on network design. GBP/LISTGBP Practical guidelines are also given for bidirectional system design. Audience:This book is aimed at designers, builders and operators of optical networks, e.g. the manufacturers of optical transmission systems, public-network operators, developers of local-area networks, cable-television operators, etcetera. The intended level of readership is graduate level in physics or electrical engineering.

Optical fiber telecommunications depend upon light traveling great distances through optical fibers. As light travels it tends to disperse and this results in some degree of signal loss. Raman amplification is a technique that is effective in any fiber to amplify the signal light as it travels through transmission fibers, compensating for inevitable signal loss.
* First comprehensive guide to Raman amplification, a technique whose use has exploded since 1997 in order to upgrade fiber capacity;
* Accessible to professionals just entering the field of optical fiber telecommunications;
* Detailed enough for experts to use as a reference.

A fibre Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fibre that reflects particular wavelengths of light and transmits all the others. As such, FBGs can be used as inline optical filters to block certain wavelengths, or as wavelength-specific reflectors. Applications include optical fibre communications, sensors and fibre lasers. This book addresses the critical challenge of developing Fibre Bragg Gratings (FBGs) for applications as sensors in harsh and space environment. Coverage ranges from the basic principles through design, fabrication, and testing to their industrial implementation. A thorough review includes the in-depth examination of the FBGs properties and the most important developments in devices and applications. A particular emphasis is given to the applications of fibre optic sensors in the space environment, which is characterized mainly by vacuum, high thermal gradients, mechanical vibrations and various types of cosmic radiation. The book concludes with a summary and overview of challenges faced by FBG technology. The book is supplemented by an extensive survey of published papers, books and conference reports. As an added benefit, the book is structured in such a way as to provide useful and in-depth training and skills development to graduate/undergraduate students, specialised engineers, and academic/industrial experts.

Shuji Nakamura's development of a blue semiconductor laser on the basis of GaN opens the way for a host of new applications of semiconductor lasers. The wavelengths can be tuned by controlling the composition. For the first time it is possible to produce lasers with various wavelengths, ranging from red through yellow and green to blue, in one substrate material. This fact, together with their high efficiency, makes GaN-based lasers very useful for a wide spectrum of applications. The second edition of this basic book on GaN-based devices has been updated and significantly extended. It includes a survey of worldwide research on GaN, as well as Nakamura's latest important developments. The reader finds a careful introduction to the physics and properties of GaN. The main part of the book deals with the production and characteristics of GaN LDs and LEDs. To complete the spectrum of applications, GaN power devices are also described.

Combining the positive characteristics of microfluidics and optics, microstructured optical fibres (MOFs) have revolutionized the field of optoelectronics. Tailored guiding, diffractive structures and photonic band-gap effects are used to produce fibres with highly specialised, complex structures, facilitating the development of novel kinds of optical fibre sensors and actuators. Part One outlines the key materials and fabrication techniques used for microstructured optical fibres. Microfluidics and heat flows, MOF-based metamaterials, novel and liquid crystal infiltrated photonic crystal fibre (PCF) designs, MOFs filled with carbon nanotubes and melting of functional inorganic glasses inside PCFs are all reviewed. Part Two then goes on to investigate sensing and optofluidic applications, with the use of MOFs in structural sensing, sensing units and mechanical sensing explored in detail. PCF's for switching applications are then discussed before the book concludes by reviewing MOFs for specific nucleic acid detection and resonant bio- and chemical sensing.

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.
