With the invention of the laser it was possible to think about a fast and efficient way to make the information transmission, thus originating the first ideas of transmission through wave guides. This led to the invention of the optical fibers, for which scientific-technological research has been constantly developed in order to improve the efficiency of information transmission for different applications. Then, various techniques and materials used for the manufacture of optical fibers have been developed, which have been improved over the years, obtaining high efficiency in the transmission of information, as well as different types of optical fiber applications. This book intends to provide the reader a review of some different fiber optic applications as well as some ideas about the future of growing in this important technological area.

All the contributing authors are experts in the field, and this book contains their latest research. This book will provide an invaluable source for researchers, engineers, and advanced students in the field of optical fibers, photonics, optoelectronics, fiber lasers, and sensors.

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.

This book presents a comprehensive account of the recent progress in optical fiber research. It consists of four sections with 20 chapters covering the topics of nonlinear and polarisation effects in optical fibers, photonic crystal fibers and new applications for optical fibers. Section 1 reviews nonlinear effects in optical fibers in terms of theoretical analysis, experiments and applications. Section 2 presents polarization mode dispersion, chromatic dispersion and polarization dependent losses in optical fibers, fiber birefringence effects and spun fibers. Section 3 and 4 cover the topics of photonic crystal fibers and a new trend of optical fiber applications. Edited by three scientists with wide knowledge and experience in the field of fiber optics and photonics, the book brings together leading academics and practitioners in a comprehensive and incisive treatment of the subject. This is an essential point of reference for researchers working and teaching in optical fiber technologies, and for industrial users who need to be aware of current developments in optical fiber research areas.

This book describes the electromagnetic theory for the propagating modes of dielectric guides with the objective of understanding the applications of these guides to a telecommunication system. Every book on classical electromagnetism introduces the metallic waveguides as an example of application of the Maxwell equations with boundary conditions. A few books summarily describe the dielectric guides. Nevertheless, following the applications of these guides in the form of optical fibers, it has become essential for a course on applied electromagnetism to cover this theory and emphasize on the dispersion minimisation which allows an extreme bandwidth. The dispersionless ?solitonic? solution is introduced to inform the reader on this new optical pulse shape which may soon ensure transoceanic communications. The study of the minimisation of the waveguide dispersion leads us, by means of several calculated frames, to the weakly-guiding condition. This essential condition for a large bandwidth fiber leads us to the introduction of the practical LP modes. In order to initiate the reader into integrated optics components, the electromagnetic solution for two coupled planar waveguides is treated in an appendix. Another appendix allows the reader to go through a quick initiation of the geometrical optics theory (essential for the study of graded-index fiber), being the iconal equation and the ray equation starting from Maxwell equation under the short wavelength approximation.
