DOWNLOAD EBOOKTwo stars of contemporary architecture explore the unique handling of light and heat in the architecture of Burkina Faso Across the African continent, but especially in the sub-Saharan regions, the light has a particularly stark quality, which becomes most apparent in relation to older buildings. Before electricity, architecture was required to make use of the sun as a light source within a building, while also protecting its inhabitants from the heat. This resulted in vernacular architecture that features very few or small openings, which consequently render the inside of a building near pitch black, while the outside is illuminated by sunshine that bears down mercilessly. On the initiative of the lighting technology company Zumtobel Group, photographer Iwan Baan (born 1975) and architect Francis Kéré (born 1965) set out to capture how the sun's natural light cycle shapes vernacular architecture in Burkina Faso with little to no artificial light sources. They traveled to three exemplary locations: communal compounds in Gando; the main mosque of Bobo Dioulasso; and the terraced houses in Dano. Baan's pictures are accompanied by architectural sketches by Francis Kéré, who himself grew up in this light environment and whose architecture is inspired by it. The stunning photographs are printed using a special technique, to give a sense of being immersed in the very light conditions documented here.

DOWNLOAD EBOOKThis book deals with applications in several areas of science and technology that make use of light which carries orbital angular momentum. In most practical scenarios, the angular momentum can be decomposed into two independent contributions: the spin angular momentum and the orbital angular momentum. The orbital contribution affords a fundamentally new degree of freedom, with fascinating and wide-spread applications. Unlike spin angular momentum, which is associated with the polarization of light, the orbital angular momentum arises as a consequence of the spatial distribution of the intensity and phase of an optical field, even down to the single photon limit. Researchers have begun to appreciate its implications for our understanding of the ways in which light and matter can interact, and its practical potential in different areas of science and technology.

DOWNLOAD EBOOKOrbital Angular Momentum States of Light provides an in-depth introduction to modelling of long-range propagation of orbital angular momentum (OAM) modes as well as more general structured light beams through atmospheric turbulence. Starting with angular spectrum method for diffraction and description of structured light states, the book discusses the technical details related to wave propagation through atmospheric turbulence. The review of historical as well as more recent ideas in this topical area, along with computer simulation codes, makes this book a useful reference to researchers and optical engineers interested in developing and testing of free-space applications of OAM states of light. Part of IOP Series in Advances in Optics, Photonics and Optoelectronics.

DOWNLOAD EBOOKFrom the early wave-particle arguments to the mathematical theory of electromagnetism to Einstein’s work on the quantization of light, different descriptions of what constitutes light have existed for over 300 years. Light – The Physics of the Photon examines the photon phenomenon from several perspectives. It demonstrates the importance of studying the photon as a concept belonging to a global vacuum (matter-free space). Divided into eight parts, the book begins with exploring aspects of classical optics in a global vacuum on the basis of free-space Maxwell equations. It then describes light rays and geodesics and presents a brief account of the Maxwell theory in general relativity. After discussing the theory of photon wave mechanics, the author gives a field-quantized description of the electromagnetic field, emphasizing single-photon quantum optics in Minkowskian space. He next focuses on photon physics in the rim zone of matter, paying particular attention to photon emission processes. He also takes a closer look at the photon source domain and field propagators, which conveniently describe the photon field propagation in the vicinity of and far from the electronic source domain. The last two parts discuss the photon vacuum and light quanta in Minkowskian space as well as two-photon entanglement, which is associated with the biphoton in space-time.

DOWNLOAD EBOOKFocusing on the unresolved debate between Newton and Huygens from 300 years ago, The Nature of Light: What is a Photon? discusses the reality behind enigmatic photons. It explores the fundamental issues pertaining to light that still exist today. Gathering contributions from globally recognized specialists in electrodynamics and quantum optics, the book begins by clearly presenting the mainstream view of the nature of light and photons. It then provides a new and challenging scientific epistemology that explains how to overcome the prevailing paradoxes and confusions arising from the accepted definition of a photon as a monochromatic Fourier mode of the vacuum. The book concludes with an array of experiments that demonstrate the innovative thinking needed to examine the wave-particle duality of photons. Looking at photons from both mainstream and out-of-box viewpoints, this volume is sure to inspire the next generation of quantum optics scientists and engineers to go beyond the Copenhagen interpretation and formulate new conceptual ideas about light–matter interactions and substantiate them through inventive applications.

DOWNLOAD EBOOKLight and light based technologies have played an important role in transforming our lives via scientific contributions spanned over thousands of years. In this book we present a vast collection of articles on various aspects of light and its applications in the contemporary world at a popular or semi-popular level. These articles are written by the world authorities in their respective fields. This is therefore a rare volume where the world experts have come together to present the developments in this most important field of science in an almost pedagogical manner. This volume covers five aspects related to light. The first presents two articles, one on the history of the nature of light, and the other on the scientific achievements of Ibn-Haitham (Alhazen), who is broadly considered the father of modern optics. These are then followed by an article on ultrafast phenomena and the invisible world. The third part includes papers on specific sources of light, the discoveries of which have revolutionized optical technologies in our lifetime. They discuss the nature and the characteristics of lasers, Solid-state lighting based on the Light Emitting Diode (LED) technology, and finally modern electron optics and its relationship to the Muslim golden age in science. The book’s fourth part discusses various applications of optics and light in today's world, including biophotonics, art, optical communication, nanotechnology, the eye as an optical instrument, remote sensing, and optics in medicine. In turn, the last part focuses on quantum optics, a modern field that grew out of the interaction of light and matter. Topics addressed include atom optics, slow, stored and stationary light, optical tests of the foundation of physics, quantum mechanical properties of light fields carrying orbital angular momentum, quantum communication, and Wave-Particle dualism in action.

DOWNLOAD EBOOKSpin angular momentum of photons and the associated polarization of light has been known for many years. However, it is only over the last decade or so that physically realizable laboratory light beams have been used to study the orbital angular momentum of light. In many respects, orbital and spin angular momentum behave in a similar manner, but t
