Black phosphorus (BP)-based two-dimensional (2D) nanomaterials are
used as components in practical industrial applications in
biomedicine, electronics, and photonics. There is a need to
controllably shape engineered scalable structures of 2D BP building
blocks, and their assembly/organization is desired for the
formation of three-dimensional (3D) forms such as macro and hybrid
architectures, as it is expected that these architectures will
deliver even better materials performance in applications.
Semiconducting Black Phosphorus: From 2D Nanomaterial to Emerging
3D Architecture provides an overview of the various synthetic
strategies for 2D BP single-layer nanomaterials, their scalable
synthesis, properties, and assemblies into 3D architecture. The
book covers defect engineering and physical properties of black
phosphorous; describes different strategies for the development of
2D nanostructures of BP with other species such as polymers,
organic molecules, and other inorganic materials; offers a
comparative study of 3D BP structures with other 3D architectures
such as dichalcogenides (TMDs, graphene, and boron nitride); and
discusses in detail applications of 3D macrostructures of BP in
various fields such as energy, biomedical, and catalysis. This is
an essential reference for researchers and advanced students in
materials science and chemical, optoelectronic, and electrical
engineering.
This is the first book to give a comprehensive and coherent account of the basic methods of characterizing a solid through its interaction with electromagnetic fields. The theoretical treatment focuses on the determination of the essential parameters of a solid (energy bands, energy levels, effective mass of electrons and holes, etc.) from measured absorption coefficients, scattering data, magneto-optical results, etc. The discussion is at an intermediate level and all the formulas are carefully deduced and explained. All types of solids (semiconductors, crystals, metals, etc.) are covered and the latest experimental results are also presented.
The present book is based on the experience of the author. The
experience is mainly the result of years of research, of consulting
work, and in participation in policy decision making in many felds,
most, but not all, related to outdoor lighting. To some degree, the
book represents the preference of the author. The selection of the
subjects is based on more than 50 years of experience of what is
desirable to know for persons engaged in scientifc research or
practical application in the felds of lighting and vision. The
subjects deal with a number of fundamental aspects. The theorists
must have them at their fngertips, whereas the practical engineers
may assume them as known in their daily work. The selection of
subjects is based in part by the questions that came to the author
over the years, but even more by the preference of the author
himself. In this respect, it is a personal book. Thus, it should be
stressed that the book is not a 'handbook' or even a 'textbook';
many subjects that commonly are treated in such books are not
included here. Not because they lack importance, but because the
author feels that they are adequately treated elsewhere. Some
relevant works are mentioned in the References. Over the years, the
author has been engaged in giving courses on vision and lighting,
lately more in particular on Masterclasses on a post-graduate or
post-doctorate level.

This textbook provides an introductory presentation of all types of
lasers. It contains a general description of the laser, a
theoretical treatment and a characterization of its operation as it
deals with gas, solid state, free-electron and semiconductor
lasers. This expanded and updated second edition of the book
presents a description of the dynamics of free-electron laser
oscillation using a model introduced in the first edition that
allows a reader to understand basic properties of a free-electron
laser and makes the difference to "conventional" lasers. The
discussions and the treatment of equations are presented in a way
that a reader can immediately follow. The book addresses graduate
and undergraduate students in science and engineering, featuring
problems with solutions and over 400 illustrations.

This title includes a number of Open Access chapters. Spectroscopy
is a powerful technique that utilizes the interaction of light with
matter. Analysis of various spectra can yield important physical
characteristics of matter, including chemical composition,
temperature, luminosity, mass, and more. The uses and implications
of spectroscopy are very broad, with practical uses in many fields
of science, including astronomy, medicine, analytic chemistry,
material science, geology, and more. Researchers are constantly
discovering new applications of spectroscopy, and it is expected to
play an ever-increasing role in nanotechnology and
superconductivity. This book brings together a diverse collection
of new research advances in spectroscopy.
This book analyzes novel possibilities offered to the
telecommunication engineer in designing tomorrow's optical
networks. Currently, optical and optoelectronic technologies make
possible the realization of high-performance optical fiber
communication systems and networks with the adoption of WDM
configurations and both linear and nonlinear optical
amplifications. The last step for increasing network throughput is
represented by the implementation of multidimensional modulation
formats in coherent optical communication systems, which enable
increasing the bit rate/channel toward 400 Gbit/s/channel and
beyond. Following this approach, the main emphasis is placed on
innovative optical modulations. Multidimensional Modulations in
Optical Communication Systems is an essential guide to the world of
innovative optical communications from the point of view of growing
capacity and security. It guides researchers and industries with
the aim to exploring future applications for optical
communications.
Since the first edition of this book was published several new
developments have been made in the field of the moire theory. The
most important of these concern new results that have recently been
obtained on moire effects between correlated aperiodic (or random)
structures, a subject that was completely absent in the first
edition, and which appears now for the first time in a second,
separate volume. This also explains the change in the title of the
present volume, which now includes the subtitle "Volume I: Periodic
Layers". This subtitle has been added to clearly distinguish the
present volume from its new companion, which is subtitled "Volume
II: Aperiodic Layers". It should be noted, however, that the new
subtitle of the present volume may be somewhat misleading, since
this book also treats (in Chapters 10 and 11) moire effects between
repetitive layers, which are, in fact, geometric transformations of
periodic layers, that are generally no longer periodic in
themselves. The most suitable subtitle for the present volume would
therefore have been "Periodic or Repetitive Layers", but in the end
we have decided on the shorter version.

the model for low-PMD ?bers; Nicolas Gisin covered the increasingly
important topic of the interaction of PMD with polarization
dependent loss. Other topics that were included in the school were:
"PMD models," which was covered byAntonio Mecozzi and Mark Shtaif;
"Interaction of PMD with nonlinearity and chromatic dispersion,"
which was covered by Curtis Menyuk; "PMD measurement techniques,"
which was covered by Paul Williams and by Marco Schiano in two
separate lectures; "Spatially resolved measurement of ?ber
polarization properties," which was covered by Luca
PalmieriandAndreaGaltarossa;"PMDimpactonopticalsystems,"whichwascovered
by Magnus Karlsson and by Francesco Matera in two separate
lectures; "Polarization effects in recirculating loops," which was
covered by Brian Marks, Gary Carter, and Yu Sun; "PMD Emulation,"
which was covered byAlan Willner and Michelle Hauer; and, ?nally,
"Applications of importance sampling to PMD," which was covered by
Gino Biondini, Bill Kath, and Sarah Fogal. Dipak Chowdhury worked
withArtis and VPI-two producers at that time of commercial software
for modeling optical ?ber communications systems-to present a
lecture that covered numerical modeling of PMD. Additionally, we
had lectures on special topics by Hermann Haus, Jim Gordon, Herwig
Kogelnik, and Carlo Someda. Finally, we had a poster session, which
gave the lecturers the opportunity to learn something from our
participants. The feedback that we received from the participants
and the lecturers was ov- whelmingly positive. This success was due
to the great time and energy that all the instructors put into
their lectures.
This self-contained monograph provides a mathematically simple and
physically meaningful model which unifies gravity,
electromagnetism, optics and even some quantum behavior. The
simplicity of the model is achieved by working in the frame of an
inertial observer and by using a physically meaningful least action
principle. The authors introduce an extension of the Principle of
Inertia. This gives rise to a simple, physically meaningful action
function. Visualizations of the geometryare obtained by plotting
the action function. These visualizations may be used to compare
the geometries of different types of fields. Moreover, a new
understanding of the energy-momentum of a field emerges. The
relativistic dynamics derived here properly describes motion of
massive and massless objects under the influence of a gravitational
and/or an electromagnetic field, and under the influence of
isotropic media. The reader will learn how to compute the
precession of Mercury, the deflection of light, and the Shapiro
time delay. Also covered is the relativistic motion of binary
stars, including the generation of gravitational waves, a
derivation of Snell's Law and a relativistic description of spin.
We derive a complex-valued prepotential of an electromagnetic
field. The prepotential is similar to the wave function in quantum
mechanics. The mathematics is accessible to students after standard
courses in multivariable calculus and linear algebra. For those
unfamiliar with tensors and the calculus of variations, these
topics are developed rigorously in the opening chapters. The
unifying model presented here should prove useful to upper
undergraduate and graduate students, as well as to seasoned
researchers.
With clear illustrations throughout and without recourse to quantum
mechanics, the reader is invited to revisit unsolved problems lying
at the foundations of theoretical physics. Maxwell and his
contemporaries abandoned their search for a geometrical
representation of the electric and magnetic fields. The
wave-particle dilemma and Bose-Einstein statistical counting have
resulted in unsatisfactory non-realistic interpretations.
Furthermore, a simple structure of the hydrogen atom that includes
hyperfine levels is still wanting. Working with the latest
experimental data in photoionics a proposed solution to the
wave-particle dilemma is suggested based on an array of
circular-polarized rays. The Bose-Einstein counting procedure is
recast in terms of distinguishable elements. Finally, a vortex
model of a 'particle' is developed based on a trapped photon. This
consists of a single ray revolving around a toroidal surface, and
allows a geometrical definition of mass, electric potential, and
magnetic momentum. With the adjustment of two parameters, values to
4 dp for the hyperfine frequencies (MHz) of hydrogen can be
obtained for which a computer program is available.
This book presents a direct measurement of quantum back action, or
radiation pressure noise, on a macroscopic object at room
temperature across a broad bandwidth in the audio range. This noise
source was predicted to be a limitation for gravitational wave
interferometers in the 1980s, but it has evaded direct
characterization in the gravitational wave community due to the
inherent difficult of reducing thermal fluctuations below the
quantum back action level. This back action noise is a potential
limitation in Advanced LIGO and Advanced Virgo, and Cripe's
experiment has provided a platform for the demonstration of quantum
measurement techniques that will allow quantum radiation pressure
noise to be reduced in these detectors. The experimental techniques
Cripe developed for this purpose are also applicable to any
continuous measurement operating near the quantum limit, and could
lead to the possibility of observing non-classical behavior of
macroscopic objects.
This text is an introductory compilation of basic concepts,
methods and applications in the field of spectroscopy. It discusses
new radiation sources such as lasers and synchrotrons and describes
the linear response together with the basic principles and the
technical background for various scattering experiments.
This book introduces the applications of laser in surface
modification, such as laser cladding of Stellite alloys and
metal-ceramic composites. Besides, nanomaterials including carbon
nanotubes and Al2O3 nanoparticles are brought into the laser
processing, to form high-temperature resistance, chemical
stability, and wear- and oxidation-resistant composite coatings.
The readers will get more knowledge about the basic principle and
application of laser cladding and laser surface hardening
technologies, and gain a deep insight into the process and
characteristics of the nanomaterial-assisted laser surface
enhancement. It provides references for the researchers, engineers,
and students in the fields of mechanical engineering, laser
processing, and material engineering.
