Book Description
We are examining a variety of novel high temperature stable polymers as new materials for second order nonlinear optical (NLO) device applications and modelling the rotational Brownian dynamics of chromophore orientation. Current polymers have sufficient optical signal generated by available chromophores, but are not practical for devices because of limitations in the temporal and thermal stability of the active chromophore orientation in the polymer matrix. This experimental and theoretical approach for developing a new class of photonic materials with superior thermal and temporal stability is a first attempt to design second order NLO polymer with controllable, tailorable local physical and electrical properties. A second, equally important goal is to theoretically and experimentally understand the basic polymer physics controlling the thermal and temporal stability of the optical chromophore orientation. This will determine not only the overall efficiency of the materials for device applications, but will generate substantial information about local mobility in high temperature stable polymers. jg p.8.

Book Description
The study of the non-linear optical properties of polymeric systems is a challenging and exciting field of research ranging from device engineering, optical measurements, chemical synthesis to design and theoretical issues. At the present time, most of the basic science needed for the synthesis of molecules and the design of devices utilizing second order optical susceptibilities is in hand, although certain issues remain to be resolved. On the other hand, many important questions regarding the design and use of third order optical susceptibilities are still unanswered. The earliest ideas of the importance of low dimensionality optical band gaps suggests the use of conjugated molecules. At present, there is considerable effort, both experimentally and theoretically, in optimizing the value of gamma for polymers or oligomers with conjugated segments, because such conjugated polymers (like polyacetylene, polythiophenes, and the poly-diacetylenes) have very large gamma. These polymers have also been under intense scrutiny because of their large conductivities when doped. Although we are beginning to understand the theoretical reasons for the various unusual properties of the materials, we do not understand the factors that limit the ultimate value of gamma. For example, what are the important structures and interactions in the molecule the prevent gamma from being as large as possible while still having a small absorption coefficient, and how can we design molecules with these constraints in mind.

Book Description
The future of information technology requires ultra high speed processing and large data storage capacity. Since the electronics technology using semi conduc tors and inorganic materials is about to reach its limits, much current research is focused on utilizing much faster photons than electrons, namely photonics. To achieve any significant effect on the actual use of the science of photonics, devel opments of more efficient photonics materials, better optical property evaluations, manufacture of devices for system applications, etc. are the subjects which need to be explored. In particular, the development of photonics materials stands in the forefront of research as this constitutes the most pertinent factor with regard to the development of ultra high speed and large capacity information processing. In this respect, there has been continuous research on photo responsive materials through molecular structure design and architecture and the results so far are very promising as functions and performances are beginning to realize their high expectations. The two special volumes "Polymers for Photonics Applications" give authorita tive and critical reviews on up to date activities in various fields of photonic poly mers including their promising applications. Seven articles have been contributed by internationally recognized and they deal with, polymers for second and third order nonlinear optics, quadratic parametric interactions in polymer waveguides, electroluminescent polymers as light sources, photoreflective polymers for holo graphic information storage, and highly efficient two photon absorbing organics and polymers.

Book Description
Mathematical methods play a significant role in the rapidly growing field of nonlinear optical materials. This volume discusses a number of successful or promising contributions. The overall theme of this volume is twofold: (1) the challenges faced in computing and optimizing nonlinear optical material properties; and (2) the exploitation of these properties in important areas of application. These include the design of optical amplifiers and lasers, as well as novel optical switches. Research topics in this volume include how to exploit the magnetooptic effect, how to work with the nonlinear optical response of materials, how to predict laser-induced breakdown in efficient optical devices, and how to handle electron cloud distortion in femtosecond processes.
