Guiding, Diffraction, and Confinement of Optical Radiation presents a wide array of research studies on optics and electromagnetism. This book is organized into eight chapters that cover the problems related to optical radiation propagation and confinement. Chapter I examines the general features of electromagnetic propagation and introduces the basic concepts pertaining to the description of the electromagnetic field and its interaction with matter. Chapter II is devoted to asymptotic methods of solution of the wave equation, with particular emphasis on the asymptotic representation of the field in the form of the Luneburg-Kline series. This chapter also looks into a number of optical systems characterized by different refractive index distributions relying on the eikonal equation. Chapter III deals with stratified media, such as the multilayered thin films, metallic and dielectric reflectors, and interference filters. Chapters IV and V discuss the problem of propagation and diffraction integrals. Chapter VI describes the scattering from obstacles and the metallic and dielectric gratings. Chapters VII considers the passive and active resonators employed in connection with laser sources for producing a confinement near the axis of an optical cavity and Fabry-Perot interferometers and mainly relies on the use of diffraction theory. Chapter VIII presents the analytic approach to the study of transverse confinement near the axis of a dielectric waveguide hinges on the introduction of modal solutions of the wave equation. This book will be of value to quantum electronics engineers, physicists, researchers, and optics and electromagnetism graduate students.

The object of this school, held at Cargese, Corsica (France) from August 12th to 24th 1991, was the presentation of the field of guided wave nonlinear optics in a comprehensive, coherent, and heuristic fashion. It seems appropriate that this school began with an historical introduction by Professor Nicolaas Bloembergen of Harvard, the acknowledged "father" of nonlinear optics, in general, and concluded with a round table discussion headed by Dr. Eric Spitz, the Scientific Director of a multinational electronics company interested in developing industrial applications of guided wave nonlinear optics. The lectures covered both the theoretical framework of the field and applications to basic scientific research, optical communications and technical instrumentation. Specific topics developed included materials for guided wave nonlinear optics, nonlinear interactions using integrated optical guides, nonlinear surface waves, solitons, fiber nonlinear optics, ultra-fast coupler switching as well as the related topic of fiber and integrated optical lasers and amplifiers. Lectures have also been devoted to squeezed states, chaos and strange attractors. The subjects covered by the school underlines one of the major ways in which this field has evolved over the past thirty some odd years. The path from the original experiments with materials requiring mega-watt power lasers to the recent developments in guided wave configurations using milliwatt power diode lasers is marked by the conjunction of ever improving fundamental scientific comprehension and continuing technological developments.

This book describes the basic properties of charged beam transport and the theory of accelerators with radiative damping. The characteristics of the third generation synchrotron radiation sources are analyzed and compared to those of the first and second generations. This is followed by the conceptual and technological problems associated with the discovery of the fourth generation sources. Within this framework, the role played by free electron laser devices is discussed and relevant theoretical and technological aspects of storage-ring and Linac-based sources are analyzed.

Optofluidics is an emerging field that involves the use of fluids to modify optical properties and the use of optical devices to detect flowing media. Ultimately, its value is highly dependent on the successful integration of photonic integrated circuits with microfluidic or nanofluidic systems. Handbook of Optofluidics provides a snapshot of the state of the field, captures current trends, and gives insight into the technology of tomorrow, which will enable researchers to tackle challenges and opportunities that it can uniquely answer. Divided into three sections, this comprehensive resource begins by introducing the scientific foundations that contribute to optofluidics. It details the connections to related research areas and reveals the scientific influences currently shaping the design and function of optofluidic systems. It provides brief reviews of those established fields from which optofluidics has evolved, putting special emphasis on how they currently intersect. This introductory material provides a basis for understanding the chapters that follow. The second section explores the synthesis of fundamental concepts to create novel devices, specifically those with optical properties that are manipulated by fluids. A main theme that runs through this part is the dynamic reconfigurability made possible by flowing and reshaping fluids. The final section looks to future applications of the field, presenting recent developments in particle detection and manipulation primarily being developed for biosensing and biomedical applications. Enhanced by thematic connections throughout the chapters that help define the field, this volume is a concise reference for the growing optofluidics community and is poised to provide a stepping stone for continued research in an area that holds promise for a myriad of applications.

Inhaltsangabe:Abstract: The ultimate miniaturization of optical devices requires structures that guide electromagnetic energy with a lateral confinement below the diffraction limit of light. In this thesis, the possibility of employing plasmon-polariton excitations in plasmon waveguides consisting of closely spaced metal nanoclusters for this purpose is examined. The feasibility of energy transport with mode sizes below the diffraction limit of visible light over distances of several hundred nanometers is demonstrated. As a macroscopic analogue to plasmon waveguides, the transport of electromagnetic energy in the microwave regime along closely spaced centimeter-scale metal rods is examined. Full-field electrodynamic simulations show that information transport occurs at a group velocity of 0.65c for fabricated structures consisting of copper rods excited at 8 GHz. A variety of passive routing structures and an all-optical modulator are demonstrated. The possibility of guiding electromagnetic energy at visible frequencies with mode sizes below the diffraction limit using plasmon waveguides is analyzed using a point-dipole model and finite-difference time-domain simulations. It is shown that energy transport occurs via near-field coupling between metal nanoparticles, which leads to coherent propagation of energy. For spherical gold particles in air, group velocities up to 0.06c are demonstrated, and a change in particle shape to spheroidal particles shows up to a threefold increase in group velocity. Pulses with transverse polarization are shown to propagate with negative phase velocities antiparallel to the energy flow. Plasmon waveguides consisting of gold and silver nanoparticles were fabricated using electron beam lithography. The key parameters that govern the energy transport are determined for various interparticle spacings and particle chain lengths using far-field measurements of the collective plasmon modes. Spherical gold nanoparticles with a diameter of 50 nm and an interparticle spacing of 75 nm show an energy attenuation of 6 dB/30 nm. This loss can be reduced by one order of magnitude by a geometry change to spheroidal particles. Using the tip of a near-field optical microscope as a local excitation source and fluorescent nanospheres as detectors, experimental evidence for energy transport over a distance of 0.5 μm is presented for plasmon waveguides consisting of silver rods with a 3:1 aspect ratio.
