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.

A text that sheds much-needed light on one of telecommunication’s brightest technologies

Fiber optics has assumed a dominant place among the available technologies to slake the ever-growing worldwide thirst for bandwidth. As miles and miles of optical fiber cable is being buried underground and under the sea, the demand for those capable of designing and installing fiber-optic systems has also grown. This book gathers all the essential information needed by the network architects, engineers, and craftspeople who plan, install, and maintain fiber-optic systems.

Requiring only a basic math and physics background, Fiber-Optic Systems for Telecommunications acts as both a tutorial and practical reference on both theory and practical applications.

It discusses:

• Loss-limited and dispersion-limited fiber links
• Optical networking
• Availability and survivability of fiber-optic networks
• Dense wave-division multiplexing (DWDM)
• Light transmission impairments, including Brillioun scattering, Raman scattering, four-wave mixing, polarization mode dispersion (PMD), and other non-linear effects
• Hybrid fiber-coax CATV networks
• Fiber-optic link budgets and tradeoffs

The text stresses design methods for achieving advanced performance on fiber-optic systems inside cost-effective limits. At the same time, a good dose of practical application is provided to the reader. For example, there is an extensive section on the application of an OTDR (optical time domain reflectometer) for performance measurement and troubleshooting of optical systems.

The book examines the maximum capacity of high-quality single-mode fiber. Here, the ITU has made some major contributions in this arena in their G.650 and G.950 recommendations. The author describes the ITU "grid" or wavelength assignment chart for the 1550 nm band. How close can these light carriers be placed before serious performance degradation occurs? He describes ultimate bit rate capacity in this band alone in the hundred of terabits reaching a final bit rate capacity possibly in the low thousands of terabits per second. The author communicates the excitement of such research in his writing.

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.

Recent earthquakes and space program-related news serve as potent reminders of the uses fiber optic technology offers to an increasingly complex world. Like living organisms sensitive to subtle changes in the environment, buildings, structures, and space vehicles can be equipped to sense and react to their surroundings by means of hair-thin glass fiber sensors embedded in structural materials and capable of carrying information and measuring changes in stress and other environmental factors. Data is collected and transmitted to a central location, where the findings are assessed and damage corrected.

Fiber Optic Smart Structures pools the expertise of thirty-three leading professionals, many of whom are pioneers in the field, and offers a comprehensive introduction to this fast growing technology. Beginning with a historical overview and a look at the background technology, the book goes on to discuss methods of embedding optical fibers in modern high-strength, lightweight composite materials; ingress and egress of optical fibers; and more specialized application concerns, including use of the Fabry-Perot interferometer and Bragg grating sensors. Lower cost options are considered in light of performance trade-offs, and broad area coverage through single-line stringing of multiple fiber sensors is compared with single and distributed sensor approaches.

The last section of the book treats the use of fiber optic smart structures in a wide range of settings. Discussions include applications in environments where high temperature and ultrasonic waves play a role; in the aerospace industry, where changes in the structural integrity of the system demand real-time automatic changes; and a rapidly emerging new direction, earthquake-resistant buildings and, along similar lines, bridges that perform self-diagnostics.

The first and only comprehensive professional reference in this important, emerging field, Fiber Optic Smart Structures is a major addition to the libraries of aerospace engineers, mechanical scientists, fiber optics researchers and engineers, architects, and structural engineers. It is also a first-rate graduate-level textbook.
