Photonics, whichusesphotonsforinformationandimageprocessing, islabeled as one of the technologies of the 21st century, for which nonlinear op- cal processes provide the key functions of frequency conversion and optical switching. Chalcogenide glasses are based on the chalcogen elements S, Se, and Te. These glasses are formed by the addition of other elements such as Ge, As, Sb, Ga, etc. These glasses are low-phonon energy materials and are generally transparentfromthevisibletoinfrared.Chalcogenideglassescanbedopedby rare-earth elements such as Er, Nd, Pr, etc., and hence numerous applications...

This book is intended to provide a much needed systematic exposition of the mathematical methods of quantum optics, something that is not found in existing books. It is primarily addressed to researchers who are new to the field. The emphasis, therefore, is on a simple and self-contained, yet concise, presentation. It provides a unified view of the concepts and the methods of quantum optics and aims to prepare a reader to handle specific situations. A number of formulae scattered throughout the scientific literature are also brought together in a natural manner. The broad plan of the book is...

From the reviews: "Takes the reader on a journey that covers all the basic science and engineering related to the topic of developing a solid-state laser for common materials processing problems. ] Entrants to the field will certainly find it a book to keep for future reference."

One aspect of the field of THz radiation is the marriage of microwave and optical techniques. By its very nature, THz radiation bridges the gap be- tween the microwave and optical regimes. The former can be characterized by the fact that most devices are comparable in size to the wavelength of the radiation. As a result, the propagation of energy in these devices is generally in the form of single-mode or low-order-mode guided waves. In contrast, the optical and infrared ranges are generally characterized by beams containing many modes, with dimensions much larger than the wavelength. Of...

Nonimaging Fresnel Lenses: Design and Performance of Solar Concentmtors; what are we talking about? It is easy to forget that you, dear reader, may not be one of those who work inexactly the same field as we do: nonimaging optics for the concentration of sunlight. You may be a researcher in some optical science interested in the core subject of this book: the world's first practical design of a nonimaging Fresnel lens concentrator. You may not be too excited about the collection of solar energy, but you would want a fuB description of the optical performance of the lens. Which you will get,...

Solitary wave physics plays a significant role from modern optical physics to optical communication, optical switching and optical storage. This book gives an updated overview of optical solitons, as a reference and guide for advanced students and scientists working in the field.

Photonic-based A/D conversion has received and continues to receive considerable attention as an alternative approach to providing enhanced resolution and speed in high-performance applications. Some of the potential advantages of using photonic technologies are high-speed clocking, broadband sampling, reduced mutual interference of signals, and compatibility with existing photonic-based systems. This book provides a comprehensive look at the application of photonic approaches to the problem of analog-to-digital conversion. It shows progress made, discusses present research, and gives a...

An attempt has been made in this edition of the book to retain the appeal of the first edition even after the addition of new material and the deletion of other matter which no longer appears essential. Major revisions have been made in almost all the chapters to include new developments. The material on EXAFS has been updated and put in a separate chapter. The chapter on experimental methods has been considerably expanded to include energy dispersive techniques. New topics like heavy-ion bremsstrah lung, X-ray lasers, resonant emission, appearance potential spectroscopy, and EXAFS of high-Tc...

This book discusses how, in random media, light dramatically changes electron- electron interaction. Despite Coulomb repulsion, the effective interaction dem- strates attraction, even under strong pumping. Light (both coherent and natural) acts like an optical motor, transporting electrons in a direction opposite to that of the electric force direction: electric current ?ows against bias and static polarization is aligned in opposition to the applied electric ?eld. The uncommon electron transport increases the initial perturbations and is the foundation of the light-driven struct- ing of a...

The resolution of any imaging microscope is ultimately limited by di?raction and can never be signi?cantly smaller than the wavelength ? of the ima- forming wave, as realized by Abbe 1] in 1870. In a visionary statement, he argued that there might be some yet unknown radiation with a shorter wa- length than that of light enabling a higher resolution at some time in the future. The discovery of the electron provided such a radiation because its wavelength at accelerating voltages above 1 kV is smaller than the radius of the hydrogen atom. The wave property of the electron was postulated in...
