Book Description
Optical network design and modeling is an essential issue for planning and operating networks for the next century. The main issues in optical networking are being widely investigated, not only for WDM networks but also for optical TDM and optical packet switching. This book contributes to further progress in optical network architectures, design, operation and management and covers the following topics in detail: Optical switching and Teabit networking; Future OTDM and packet switched networks; WDM ring networks; Optical interworking and `packets over wavelength'; Hybrid and switchless networks; Medium access protocols for optical LANs and MANs. This book contains the selected proceedings of the Fourth International Working Conference on Optical Network Design and Modeling, which was sponsored by the International Federation for Information Processing (IFIP), and held in February 2000, in Athens, Greece. This valuable new book will be essential reading for academic researchers and practitioners working in computer science, electrical engineering, and communications.

Book Description
This book summarizes the proceedings of the invited talks presented at the International Symposium on New Trends in Optical Soliton Transmission Systems held in Kyoto during November 18 - 21, 1997. As a result of worldwide demand for ultra high bitrate transmissions and increased scientific interest from the soliton community, research on optical solitons in fibres has made remarkable progress in recent years. In view of these trends, the Research Group for Optical Soliton Communications (ROSC), chaired by Akira Hasegawa, was established in Japan in April 1995 to promote collaboration and information exchange among communication service companies, industries and academic circles in the theory and application of optical solitons. This symposium was organized as a part of the ROSC activities. As with the 1 st ROSC symposium, this symposium attracted enthusiastic response from worldwide researchers involved in the subject of soliton based communications and intensive discussions were held throughout the symposium. Particular emphases were made to dispersion managements of soliton transmission. I would like to note that in the }'t symposium the (adiabatic) dispersion managements just began to appear in reducing radiation at amplifiers and reducing collision effects in WDM system. These have become standard this time, but in addition new, non-adiabatic dispersion managements have been introduced independently by various scientists all over the world.

Book Description
Superionic Solids and Solid Electrolytes: Recent Trends describes the fundamental aspects, unique properties, and potential applications of superionic solids and solid electrolytes. These materials significantly contribute to the development of the solid state ionics technology. This book is divided into 17 chapters, and begins with an overview of various materials, such as glasses, heterogeneous or dispersed phase conductors, proton conductors, Nasicon, and fluorites. These topics are followed by a discussion on the problems related with entropy effects, subsurface space charge, and defect formation parameters. Significant chapters deal with the phenomenological, fractal, molecular dynamics, fluctuations, and correlations in superionic solid and solid electrolyte materials. A chapter tackles the solid state battery applications of solid electrolytes. This text ends with a chapter on the prediction of the potentials of activity in superionics. This book will be of value to graduate students and researchers who are interested in the solid state ionics technology.

Book Description
Despite its limitation in terms of surface covered area, the PLD technique still gathers interest among researchers by offering endless possibilities for tuning thin film composition and enhancing their properties of interest due to: (i) the easiness of a stoichiometric transfer even for very complex target materials, (ii) high adherence of the deposited structures to the substrate, (iii) controlled degree of phase, crystallinity, and thickness of deposited coatings, (iv) versatility of the experimental set-up which allows for simultaneous ablation of multiple targets resulting in combinatorial maps or consecutive ablation of multiple targets producing multi-layered structures, and (v) adjustment of the number of laser pulses, resulting in either a spread of nanoparticles, islands of materials or a complete covering of a surface. Moreover, a variation of PLD, known as Matrix Assisted Pulsed Laser Evaporation, allows for deposition of organic materials, ranging from polymers to proteins and even living cells, otherwise difficult to transfer unaltered in the form of thin films by other techniques. Furthermore, the use of laser light as transfer agent ensures purity of films and pulse-to-pulse deposition allows for an unprecedented control of film thickness at the nm level. This Special Issue is a collection of state-of-the art research papers and reviews in which the topics of interest are devoted to thin film synthesis by PLD and MAPLE, for numerous research and industry field applications, such as bio-active coatings for medical implants and hard, protective coatings for cutting and drilling tools withstanding high friction and elevated temperatures, sensors, solar cells, lithography, magnetic devices, energy-storage and conversion devices, controlled drug delivery and in situ microstructuring for boosting of surface properties.

Book Description
The field of nonlinear optics, which has undergone a very rapid development since the discovery of lasers in the early sixties, continues to be an active and rapidly developing - search area. The interest is mainly due to the potential applications of nonlinear optics: - rectly in telecommunications for high rate data transmission, image processing and recognition or indirectly from the possibility of obtaining large wavelength range tuneable lasers for applications in industry, medicine, biology, data storage and retrieval, etc. New phenomena and materials continue to appear regularly, renewing the field. This has proven to be especially true over the last five years. New materials such as organics have been developed with very large second- and third-order nonlinear optical responses. Imp- tant developments in the areas of photorefractivity, all optical phenomena, frequency conv- sion and electro-optics have been observed. In parallel, a number of new phenomena have been reported, some of them challenging the previously held concepts. For example, solitons based on second-order nonlinearities have been observed in photorefractive materials and frequency doubling crystals, destroying the perception that third order nonlinearities are - quired for their generation and propagation. New ways of creating and manipulating nonl- ear optical materials have been developed. An example is the creation of highly nonlinear (second-order active) polymers by static electric field, photo-assisted or all-optical poling. Nonlinear optics involves, by definition, the product of electromagnetic fields. As a con- quence, it leads to the beam control.
