Provides an overview of Fiber Bragg Gratings (FBGs), from fundamentals to applications Evaluates the advantages and disadvantages of particular applications, methods and techniques Contains new chapters on sensing, femtosecond laser writing of FBGs and poling of glass and optical fibers Includes a special version of the photonic simulator PicWave(tm), allowing the reader to make live simulations of many of the example devices presented in the book. This fully revised, updated and expanded second edition covers the substantial advances in the manufacture and use of FBGs in the years since the publication of the pioneering first edition. It presents a comprehensive treatise on FBGs and addresses issues such as the merits of one solution over another; why particular fabrication methods are preferred; and what advantages a user may gain from certain techniques. Beginning with the principles of FBGs, the book progresses to discuss photosensitization of optical fibers, Bragg grating fabrication and theory, properties of gratings, specific applications, sensing technology, glass poling, advances in femtosecond laser writing of Bragg gratings and FBG measurement techniques. In addition to material on telecommunications usage of FBGs, application areas such as fiber lasers and sensors are addressed in greater detail. This special version of Picwave is limited to modelling only the passive fibre devices covered in this book. However the full PicWave package is capable of modelling other non-linear and active devices such as laser diodes and SOAs as discussed in Chapter 8. More information about PicWave can be found at www.photond.com/products/picwave.htm. In addition to researchers, scientists, and graduate students, this book will be of interest to industrial practitioners in the field of fabrication of fiber optic materials and devices. Raman Kashyap, Canada Research Chair holder on Future Photonics Systems, and Professor at École Polytechnique, University of Montréal since 2003, has researched optical fibers and devices for over 30 years. He pioneered the fabrication of FBGs and applications in telecommunications and photonics.

Polymer optical fibers (POFs) have been regarded as a viable alternative to silica fibers in a variety of sensing applications. Fiber optic sensors offer key advantages over other sensing technologies, which include immunity to electromagnetic interference, compact, lightweight, multiplexing capability, and higher sensitivity. This book gives an overview of the polymer optical fiber Bragg grating (POFBG) technology over the last 20 years, covering aspects related to the fiber Bragg grating fabrication and also sensing applications. The book is split into five chapters, and it is written in such a way that can provide a comprehensive and simple route to new users, scientists and engineers working or wishing to work in the field of POFBGs: Describes the systems commonly employed for producing fiber Braggs gratings (FBGs) in silica fibers that can be used for the production of POFBGs; Explores different laser sources for the inscription of POFBGs; Explores the capability of using this technology at the visible and infrared region, in different fiber types (e.g., step-index, microstructured, unclad, highly birefringent) and in fibers composed of different polymer materials such as PMMA, doped PMMA, PS and ZEONEX; Reports the fabrication of different types of POF gratings, such as uniform, phase-shifted, tilted, chirped, and long-period gratings; Shows the opportunities of POFBGs for a variety of sensing applications. The insight to the use of POFBGs provides a vision for the opportunities of this fiber optic technology.
