The optical fiber based supercontinuum source has recently become a
significant scientific and commercial success, with applications
ranging from frequency comb production to advanced medical imaging.
This one-of-a-kind book explains the theory of fiber supercontinuum
broadening, describes the diverse operational regimes and indicates
principal areas of applications, making it a very important guide
for researchers and graduate students. With contributions from
major figures and groups who have pioneered research in this field,
the book describes the historical development of the subject,
provides a background to the associated nonlinear optical
processes, treats the generation mechanisms from continuous wave to
femtosecond pulse pump regimes and highlights the diverse
applications. A full discussion of numerical methods and
comprehensive computer code are also provided, enabling readers to
confidently predict and model supercontinuum generation
characteristics under realistic conditions.
An optical fibre is a glass or plastic fibre designed to guide
light along its length by confining as much light as possible in a
propagating form. In fibre with large core diameter, the
confinement is based on total internal reflection. In smaller
diameter core fibres, (widely used for most communication links
longer than 200 meters) the confinement relies on establishing a
waveguide. Fibre optics is the overlap of applied science and
engineering concerned with such optical fibres. Optical fibres are
widely used in fibre-optic communication, which permits
transmission over longer distances and at higher data rates than
other forms of wired and wireless communications. They are also
used to form sensors, and in a variety of other applications. The
term optical fibre covers a range of different designs including
graded-index optical fibres, step-index optical fibres,
birefringent polarisation-maintaining fibres and more recently
photonic crystal fibres, with the design and the wavelength of the
light propagating in the fibre dictating whether or not it will be
multi-mode optical fibre or single-mode optical fibre. Because of
the mechanical properties of the more common glass optical fibres,
special methods of splicing fibres and of connecting them to other
equipment are needed. Manufacture of optical fibres is based on
partially melting a chemically doped pre-form and pulling the
flowing material on a draw tower. Fibres are built into different
kinds of cables depending on how they will be used. This new book
presents the latest research in the field.
This non-technical book examines Britain's cable communications
industry -- the leader in Europe with a powerful fibre network,
capable of delivering hundreds of channels, cable TV, advanced
telephony and the new interactive services.
Ian Scales who has been covering the industry since the early
1980s, explains why cable is a major factor in engineering the UK's
current pole position on the European Information Superhighway. He
reviews the basics of the technology, its history and how services
might evolve as the market in both entertainment and two-way
communications between people and businesses continues to boom.
This book presents a comprehensive introduction to the design of
compact and broadband fiber and waveguide devices using
active-ion-doped photonic glasses. Combining cutting-edge theory
with new applications, it shows how the complementarity of emission
spectra of different active ions can be used in broadband fiber
amplifiers and optical fiber communication, and describes how the
quantum cutting of active ions can improve the match between the
solar spectrum and the responsiveness of silicon cells.
Mathematical modeling is used to predict the performance of
photonic fiber and waveguide devices, and experimental data from
glass doped with rare-earth ions is included. Offering unique
insights into the state-of-the-art of the field, this is an ideal
reference for researchers and practitioners, and invaluable reading
for students in optoelectronics, electrical engineering, and
materials science.
The Centre for Smart Infrastructure aims to develop and
commercialise emerging technologies which will provide radical
changes in the construction and management of infrastructure,
leading to considerably enhanced efficiencies, economies and
adaptability. This book offers comprehensive guidance on
developments of distributed optical fibre sensing. Smart monitoring
for performance-based design is increasingly being recognised as an
essential tool for improving construction processes, delivering
efficiency and reducing over specification. On the other hand, the
high level of maintenance required to preserve our ageing
infrastructure and run it at full capacity has created a demand for
structural health monitoring or performance-based maintenance.
Recent advances in the development of low-loss optical fibers have revolutionized the field of telecommunications, and fiber-based networks form a key part of international communications systems. This book introduces the physical principles of optical fibers, and details their use in sensor technology and modern optical communication systems. The authors begin by setting out the basic propagation characteristics of single mode and multimode optical fibers. In later chapters they cover optical sources, optical detectors, and fiber-optic communication system design. They also treat a wide variety of related topics such as doped fiber amplifiers, dispersion compensation, fiber sensors, and measurement techniques for the characterization of optical fibers. The book emphasizes physical and engineering aspects of the subject. It will be an ideal textbook for undergraduate or graduate students taking courses in optical fiber communications, photonics, or optoelectronics.
Applications of Nonlinear Fiber Optics, Third Edition presents
sound coverage of the fundamentals of lightwave technology, along
with material on pulse compression techniques and rare-earth-doped
fiber amplifiers and lasers. The book's chapters include
information on fiber-optic communication systems and the ultrafast
signal processing techniques that make use of nonlinear phenomena
in optical fibers. This book is an ideal reference for R&D
engineers working on developing next generation optical components,
scientists involved with research on fiber amplifiers and lasers,
graduate students, and researchers working in the fields of optical
communications and quantum information.
