Novel Photorefractive and Electro-Optic Polymers-Rational Designs, Synthesis and Mechanism


Book Description

This report describes our effort in the past three years on synthesis and characterization of novel photorefractive polymer system. Two major systems were developed, one of which combined the ionic transition metal complexes and a conjugated polymer backbone bearing NLO chromophores to manifest large photorefractive effect. Another is a molecular material containing oligothiophene and a nonlinear optical (NLO) chromophore. A large net optical gain (>200/cm) at a zero electric field was observed in the metal containing system. In the molecular system, a net optical gain of 83/cm and a diffraction efficiency of nearly 40% were obtained in a film made from this molecule under an applied field of 706 kv/cm. A fast response time of for the grating formation, 42 ms under 616 kv/cm, was observed.

Nonlinear Optics of Organic Molecules and Polymers


Book Description

The field of nonlinear optics emerged three decades ago with the development of the first operating laser and the demonstration of frequency doubling phenomena. These milestone discoveries not only generated much interest in laser science, but also set the stage for future work on nonlinear optics. This book presents an excellent overview of the exciting new advances in nonlinear optical (NLO) materials and their applications in emerging photonics technologies. It is the first reference source available to cover every NLO material published through 1995. All theoretical approaches, measurement techniques, materials, technologies, and applications are covered. With more than 1,800 bibliographic citations, 324 figures, 218 tables, and 812 equations, this book is an invaluable reference source for graduate and undergraduate students, researchers, scientists and engineers working in academia and industries in chemistry, solid-state physics, materials science, optical and polymer engineering, and computational science.
