Electromagnetic surface excitations : proceedings of an international summer school at the Ettore Majorana Centre, Erice, Italy, July 1-13, 1985 by R. F Wallis( Book )

5 editions published in 1986 in English and held by 168 WorldCat member libraries worldwide

This volume is based on lectures and contributed papers presented at the Eighth Course of the International School of Materials Science and Tech nology that was held in Erice, Sicily, Italy at the Ettore Majorana Centre for Scientific Culture during the period 1-13 July 1985. The subject of the course was "Electromagnetic Surface Excitations". Forty lectures were given by eleven distinguished scientists and engineers from France, Italy, the United Kingdom, and the United States. In addition to the lectur ers, approximately fifty participants representing eleven different countries throughout the world t. ook part in the course. Short contributed papers were presented by seventeen participants on the results of their own re search. The subject of the Course is of great importance for both pure science and for practical applications such as telecommunications. A technolog ical revolution is occurring in which the transmission of information by means of electrical currents travelling in copper wires is being replaced by transmission by means of light travelling in objects known as optical wave guides. The manipulation and processing of the light signals prior and subsequent to transmission through the wave guide has resulted in a technology often referred to as integrated optics. Important to the opera tion of integrated optics devices is the behavior of electromagnetic waves near surfaces and interfaces. One of the goals of the course was to further the dialogue between engineers and physicists in common areas of interest related to the propagation of electromagnetic waves along surfaces
Nonlinear surface electromagnetic phenomena by H.-E Ponath( Book )

8 editions published between 1991 and 2012 in English and held by 161 WorldCat member libraries worldwide

In recent years the physics of electromagnetic surface phenomena has developed rapidly, evolving into technologies for communications and industry, such as fiber and integrated optics. The variety of phenomena based on electromagnetism at surfaces is rich and this book was written with the aim of summarizing the available knowledge in selected areas of the field. The book contains reviews written by solid state and optical physicists on the nonlinear interaction of electromagnetic waves at and with surfaces and films. Both the physical phenomena and some potential applications are dealt with
Nonlinear optics : phenomena, materials, and devices by G. I Stegeman( Book )

11 editions published in 2012 in English and held by 107 WorldCat member libraries worldwide

"This book is based on tried and tested courses taught by the author, George Stegeman, who is one of the experimental pioneers in nonlinear optics. The book starts with second order phenomena, goes on to explain the derivation of nonlinear susceptibilities, and finishes with a thorough discussion of third order nonlinear effects. Included is a simple "electron on a spring" model which helps readers begin their journey through the field of nonlinear optics"--
Anisotropic and nonlinear optical waveguides( Book )

9 editions published in 1992 in English and held by 100 WorldCat member libraries worldwide

Dielectric optical waveguides have been investigated for more than two decades. In the last ten years they have had the unique position of being simultaneously the backbone of a very practical and fully developed technology, as well as an extremely exciting area of basic, forefront research. Existing waveguides can be divided into two sets: one consisting of waveguides which are already in practical use, and the second of those which are still at the laboratory stage of their evolution. This book is divided into two separate parts: the first dealing with anisotropic waveguides, and the second with nonlinear behaviour. Nonlinear behaviour in optical waveguides is a topic of current research interest, an effect eagerly being sought in waveguides. The relative importance of nonlinearity versus anisotropy in theoretical papers changes enormously from problem to problem. Many theories can be quite useful and enlightening even though they neglect entirely one of the two aspects. Scientists may find their research work leading them in the near future to deal simultaneously with anisotropy and nonlinearity in order to pursue their own investigations. This book will be of interest to researchers who first need to understand the individual topics, suitably chosen from the two parts of this work, thus providing them with the necessary ingredients to pursue their explorations

Signal Processing with Degenerate Four-Wave Mixing( Book )

2 editions published between 1986 and 1987 in English and held by 2 WorldCat member libraries worldwide

In light of this need a major part of our research program in the last year has been the continuation of research into the semiconductor-doped glass material system. Bulk DFWM an photoluminescence experiments on these materials determined that they have a large nonlinear index of refraction (n(2) approx 10 to the minus 14th power sq m) with fast response times (r less than 16 psec) required for high speed optical signal processing. Along with collaborators in the University of Galsgow we successfully developed a successful ion-exchange (Na+:K+) technique for producing low-loss optical waveguides in these materials, the details of which are in the enclosed reprint

Novel Frequency Conversion Phenomena Based on Poled Polymers( Book )

2 editions published in 1997 in English and held by 1 WorldCat member library worldwide

The technology of second harmonic generation in channel waveguides made from poled polymers was developed for interaction geometries appropriate for (1) cascading and wavelength shifting, and (2) for wavelength demultiplexing. For fundamental beams which generate a harmonic along the same propagation direction, various phase matching geometries were studied which relied on periodically modulating the linear refractive index and/or the nonlinearity (QPM) in DANS. Although this approach with interdigitated poling electrodes did produce the best results ever reported in polymeric systems, it was not competitive with those in the ferroelectric QPM-LiNbO3. The best results were obtained using modal phase matching in which a low order fundamental waveguide mode was velocity matched to a higher order harmonic mode. By using multiple layers with successive layers poled in opposite directions, a figure of merit equal to LiNbO3 was achieved in the polymer DR1. However, the large losses at the second harmonic reduced the effective sample length and hence the absolute conversion efficiency. For oppositely propagating fundamental inputs, a geometry appropriate to demultiplexing, alternatively poled layers led to the largest conversion efficiencies for any material system for second harmonic beams radiated normal to the waveguide surfaces

Large Non Resonant Nonlinearities in DANS Based Polymer Waveguide: Role of Microscopic Cascading( Book )

1 edition published in 1992 in English and held by 1 WorldCat member library worldwide

Polymers can exhibit both large and fast nonresonant third-order nonlinearities which rely on Pi-electron delocalization and conjugation, as well as good physical and chemical properties suitable for the fabrication of nonlinear integrated optics devices. Soluble polymers with strong charge transfer states such asymmetrically substituted 4-dialkylamino-4'-nitro-stilbene (DANS) and 4-dialkylamino-4'-nitro-diphenylbu-tadiene (DAN2) side-groups were originally developed for electro-optic applications because of their large second order nonlinearities and low propagation losses in waveguide form. Using nonlinear grating coupling we found a large value for n sub 2, the Kerr coefficient. Measurements and analysis of the spectral dispersion of third harmonic generation indicate that the dominant contribution to the nonlinearity is due to the local cascading of second order nonlinearities

Elastic Properties of Metallic Superlattices( )

2 editions published in 1994 in English and held by 0 WorldCat member libraries worldwide

This Final Report describes some of the significant results from our research program on the elastic properties of metallic multi-layers and superlattices. This work resulted in 20 papers (listed at the end of this report) submitted to various refereed journals, as well as 10 invited talks at international conferences. The elastic properties of composition-modulated metallic superlattice films have received considerable attention over the past fifteen years following the initial reports of anomalous enhancements of some elastic moduli as measured by the bulge tester method. For example, it was reported that the Ag/Pd system exhibited an increase of the biaxial modulus of up to 500%. However, more recent measurements failed to reproduce such large enhancements of elastic moduli in the systems for which the elastic anomaly was originally measured. The elastic anomalies observed in subsequent experiments were considerably smaller, although they showed a functional dependence on A, with either stiffening or softening taking place in different material systems for A in the range of --2540 A. In apparent contrast, some Brillouin light scattering (BLS) measurements have shown a softening of the shear elastic constant c44 in some bcc/fcc systems, although a stiffening was found in Au/Cr. Because of these apparent contradictions, coupled with the importance of this problem, we initiated a program with ONR funding to investigate these effects. In this report, we review some of our significant results obtained with ONR funding, on the structural and elastic properties observed metallic superlattice films
