The purpose of this symposium was to provide an interdisciplinary forum for the discussion of recent advances in research on electronic and photonic devices made with organic and polymeric materials. The field of organic optical materials is rapidly growing, and new advances are being made both in attaining a deeper understanding of device phenomena and in designing improved materials for thin films, fibers, and waveguides. The symposium provided a highly interactive forum for an update in the connected areas of photonics with organic materials. The Meeting was highlighted by several major advances in various fields ranging from nonlinear absorbers and electro-optic polymers, to photorefractive polymers, organic transistors, and electroluminescent materials and devices for displays. The symposium highlighted developments in materials chemistry and physics relevant to such devices and struck a balance between basic science and technology.

The field of organic optical materials is rapidly growing, and advances are being made both in attaining a deeper understanding of device phenomena and in designing improved materials for thin films, fibers and waveguides. This book offers an interdisciplinary discussion of research on electronic and photonic devices made with organic and polymeric materials. The 1999 MRS Spring Meeting was highlighted by several major advances in fields ranging from nonlinear absorbers and electro-optic polymers, to photorefractive polymers, organic transistors and electroluminescent materials and devices for displays. This book highlights developments in materials chemistry and physics relevant to such devices and strikes a balance between basic science and technology. Topics include: nonlinear optical materials; photorefractive polymers; and electronic and light-emitting materials.

The field of nonlinear optics developed gradually with the invention of lasers. After the discovery of second-harmonic generation in quartz, many other interesting nonlinear optical processes were rapidly discovered. Simultaneously theoretical programmes for the understanding of nonlinear optical phenomena were stimulated in accordance to develop structure-property relationships. In the beginning, research advances were made on inorganic ferroelectric materials followed by semiconductors. In the 1970's, the importance of organic materials was realised because of their nonlinear optical responses, fast optical response, high laser damage thresholds, architectural flexibility, and ease of fabrication. At present materials can be classified into three categories - inorganic ferroelectrics, semiconductors, and organic materials. Advances have also been made in quantum chemistry approaches to investigate nonlinear optical susceptibilities and in the development of novel nonlinear optical devices. Generally, inorganic and organic nonlinear optical materials and their related optical processes are reported in separate meetings. This book collects for the first time papers covering the recent developments and areas of present research in the field of nonlinear optical materials.

Just after the International Quantum Electronics Conference, which took place in Tokyo, July 18-21, 1988, a symposium on "Nonlinear Optics of Org~ics and Semiconductors" was held on the Hongo campus of the University of Tokyo on July 25 and 26, 1988. Recently, nonlinear optical materials have started to attract the attention of many scientists, not only in the field of quantum electronics but also in organic chemistry, and solid-state physics, especially semiconductor physics. Therefore this area of investigation is really interdisciplinary and necessitates understanding from different viewpoints for continuous growth of the research activity in the field. This book contains many papers written by scientists active in the field of nonlinear optics of organic materials and semiconductors. The first two parts of the book discuss mainly the basic physics of nonlinear optics of semiconduc tors, including bulk and quantum well structure semiconductors. The papers in Parts ill-VIII concern mainly organic materials. They include the calculation of molecular polarizability, synthesis, the measurement of optical nonlinearity and characterization. The final part is on potential device applications. The symposium was organized in collaboration with Prof. Shinsuke Umegaki of Tokyo Technical Institute, and Dr. Hachiro Nakanishi of the Research Institute of Polymers and Textiles. Preparations for the conference were made with the help of Dr. Masayuki Yoshizawa, Miss Nanae Indou, Mrs. Yoko Sasaki and graduate students (Mrs. T. Hattori, M. Terauchi, K. Ichimura, A. Terasaki, K.

Organic Nonlinear Optical Materials provides an extensive description of the preparation and characterization of organic materials for applications in nonlinear and electro-optics. The book discusses the fundamental optimization and practical limitations of a number of figures of merit for various optical parameters and gives a clinical appraisal o
