Introduction to Nonlinear Optical Effects in Molecules and Polymers

Molecular Dynamics in Restricted Geometries Edited by Joseph Klafter and J. M. Drake This investigation of the chemistry and physics of complex systems focuses on the role of spatial restrictions on molecular movement. A practical source-book for researchers in chemical physics, chemical engineering, and condensed matter physics, and for graduate students in these fields, it covers a broad range of topics and critically evaluates methods as they are employed. Among the many topics it covers are: relaxation and diffusion in restricted geometries, excitation energy transfer and photoinduced electron transfer phenomena in some confined systems, electron excitation transport in micelles, polymers and multilayers, and electron excitation transport on polymer chains. 1989 (0 471-60176-4) 437 pp. Basis and Formulation of Nonlinear Optics.

Index. About the authors PARAS N. PRASAD is Professor of Chemistry and Director of Photonics Research Laboratory at the State University of New York at Buffalo, where he has been since 1974. He is the coeditor of the books Nonlinear Optical and Electroactive Polymers and Nonlinear Optical Effects in Organic Polymers. Dr. Prasad was an Alfred P. Sloan Fellow and received two gold medals from Bihar University for standing first in his MSc and BSc exams. He received a PhD in chemistry from the University of Pennsylvania in 1971. DAVID J. WILLIAMS has been Head of Molecular and Optical Electronics Laboratory at Eastman Kodak Company since 1985. Previously, he was manager of the Chemical Research Area at Xerox Corporation. He is the editor of the book Nonlinear Optical Properties of Organic and Polymeric Materials and a member of the American Chemical Society and Optical Society of America. Dr. Williams received his PhD in chemical physics from the University of Rochester in 1968. Introduction to Nonlinear Optical Effects in Molecules and Polymers is the first book devoted exclusively to one of the fastest growing areas of chemistry, optics, and materials science: nonlinear optics in organic materials. Nonlinear optics is a new frontier of science and technology that is playing a major role in the emerging technology of photonics. Photonics, which uses photons for information and image processing, has been labeled the technology of the 21st century, and nonlinear optical processes provide its key functions of frequency conversion and optical switching. Organic materials, including polymers, are a major material class for these optical applications, and their chemical structures can be optimized through molecular design and synthesis. Because they offer the flexibility, both at the molecular and bulk levels, to optimize the nonlinearity and other required properties for device applications, molecular materials and polymeric systems have emerged recently as a new class of promising nonlinear optical materials. Written to be used as a reference book by researchers of varied backgrounds, this book minimizes detailed mathematical presentation and rather emphasizes concepts. It deals with the mathematical and physical concepts in a conceptual manner so the field can be grasped without first having to master electromagnetic theory. It begins with a brief introduction to the principles of linear and nonlinear optics. Attention is then focused on the electronic and structural aspects of organic materials that make them of interest. Various experimental techniques for characterizing nonlinear optical effects are described, then it explores their various applications. This book is the first to comprehensively focus on issues associated with development of new organic materials. Introduction to Nonlinear Optical Effects in Molecules and Polymers provides a valuable perspective and introduction to the principles, basic concepts, measurements, molecular engineering, current status, future directions, experimental and characterization techniques, and materials surveys of nonlinear optical processes. It will be of the greatest interest for those professionals and advanced students of chemistry (organic, photo, and polymer), physics, optics, and engineering (electrical, materials science, and device).
