Book Description
Have you ever wondered what is the most distant source of light we can see, or how a star shines? Did you know that black holes can blaze like cosmic beacons across intergalactic space, and that ancient radio waves might herald the ignition of the very first stars? Have you ever thought about what light really is? Five Photons explains what we know about the universe through five different journeys of light across space and time. They are tales of quantum physics and general relativity, stars and black holes, dark matter and dark energy. Let yourself be swept away on a journey of discovery towards a deeper understanding of the cosmos.

Book Description
Since the first stimulated emission pumping (SEP) experiments more than a decade ago, this technique has proven powerful for studying vibrationally excited molecules. SEP is now widely used by increasing numbers of research groups to investigate fundamental problems in spectroscopy, intramolecular dynamics, intermolecular interactions, and even reactions. SEP provides rotationally pre-selected spectra of vibrationally highly excited molecules undergoing large amplitude motions. A unique feature of SEP is the ability to access systematically a wide variety of extreme excitations localized in various parts of a molecule, and to prepare populations in specific, high vibrational levels. SEP has made it possible to ask and answer specific questions about intramolecular vibrational redistribution and the role of vibrational excitation in chemical reactions.

Book Description
Contemporary physics is not able to determine the true content of the universe. At the present time we do not have clear scientific answers to what are the universe, particle, mass, energy, gravity, infinity, space and many more components of the universe. They are left unanswered and opened for everybody to guess. We are given descriptive definitions based on study of particle motions so we have a glimpse of what the universe does but not even a rudimentary concept of what the universe is. This scientific insecurity gives various ideologists open field to preach their doctrines about what is the universe and what are humans in it. My background is in philosophy and physics and I spent most of my life in researching the universe content and properties. I found the real, logical answers, which as it happened do not comply with what physics at the present time calls The Standard Model of the Universe. Most of hypothetical work accomplished in this field became somehow an ideology of the modern science and a dogma of a sort. Society passionately protects its dogmas as it did in Galileos time so my theory will provoke resistance among some contemporary physicists and ideologists because it is not based on quantum mechanics mathematics and principle of uncertainty. Subject of quantum mechanics is universe behaviour motions quantities. It only recognizes what the universe does and it cannot even express what universe is. For the real answers I turned to logic and by a painstaking logical process of simplification, comparison and elimination I came to conclusions which are rather surprising, original and are supported by all true laws of physics and correctly interpreted experiments. I replaced quantum mechanics with natural logic in the new model of the universe. None of this has ever been published.

Book Description
In this book, the issues regarding the theory of optics and quantum optics of spherical multilayered systems are studied. In such systems the spatial scale of layers becomes comparable with the wavelength of radiation, which complicates the analysis of important quantities such as reflectivity and transmission.

Book Description
On-Chip Photonics: Principles, Technology and Applications reviews advances in integrated photonic devices and their demonstrated applications, including ultrafast high-power lasers on a chip, mid-infrared and overtone spectroscopies, all-optical processing on a chip, logic gates on a chip, and cryptography on a chip. The summaries in the book's chapters facilitate an understanding of the field and enable the application of optical waveguides in a variety of optical systems. The ultimate goal of this work is aimed at accelerating the transition of on-chip photonics from academia to the industry. Each chapter, where appropriate, provides an overview of the computational tools, fabrication methods, and suggestions for the realization of on-chip photonic devices. - Introduces advanced concepts of passive and active on-chip photonic components - Discusses emerging applications of on-chip photonics, quantum technologies, computing, and more - Reviews materials, computational tools, and suggestions for the realization of on-chip photonic devices
