Photon-Working Switches
This book focuses on photoswitches. The objective of the book is to introduce researchers and graduate course students who are interested in "photon-working switches" not only to the fundamentals but also to the latest research being carried out in this field. Light can reach a target substrate without any physical contact to deliver energy. The energy can induce changes in the structure of the molecules included in the substrate so that its properties and functions are made switchable by light irradiation. When a substrate is able to revert to its original state, this system can be regarded as a "photon-working switch". The terms "photon-working switches" or "photoswitches" are almost equivalent in meaning to "photochromism"; however, they focus on the "switching of functions" of chemical species rather than their "reversible transformation". Most of the authors of this volume are members of PHENICS, an international research group on organic molecular photoswitches composed of research institutions from France, Japan, Russia, China and Germany. Since its inception in 2008, PHENICS has promoted active research to develop the field. This book commemorates the group's eighth year of collaborative research.
Diarylethene Molecular Photoswitches
A comprehensive review to the synthesis, properties, and applications of diarylethene-based molecular photoswitches Diarylethene Molecular Photoswitches: Concept and Functionalities provides the fundamental concepts of molecular photoswitches and includes information on how the bistable photoswitches of diarylethenes modulate the functions of materials and biological activities. Written by Masahiro Irie (the inventor of photochromic diarylethene compound), the book explores the reaction mechanism, photoswitching performance, photoswitchable crystals, and the myriad applications of diarylethenes based photoswitches. This book offers academics, chemists, and engineers an essential resource for understanding the molecular photoswitches and provides a guide to the development of new photoresponsive materials. The author explores the applications based on diarylethene and its dirivatives to Field-Effect Transistors, Metal-Organic Frameworks including nanoparticles, super-resolution fluorescence microscopies, drug release, and self-healing materials. This important book: * Offers a guide to diarylethene derivatives, the most widely studied compounds worldwide among the photochromic compounds * Includes the basic concepts of molecular photoswitches * Explores the myraid applications grounded in diarylethene and its derivatives * Presents an authortative text from the inventor of the photochromic diarylethene compound Written for materials scientists, organic, polymer, and physical chemists, and electronics engineers, Diarylethene Molecular Photoswitches offers an introduction to the topic and includes recent developments in the field.

Optical Switching is the most comprehensive and up to date reference book on its subject. After three decades of research and development efforts, optical switching has started to be deployed in cutting-edge networking initiatives. The optical devices, optical networks, and telecommunications/data networking communities are in need of a reference book that compiles diverse optical switching research, from device technologies to system and network architectures, into one properly structured volume. This book provides such a service to these communities. The book is structured into three parts. The first part provides the foundation for understanding the potential role of optical switching in communication networks. The second part is focused on optical switching technologies and on devices based upon them. Theories, operation principles, and fabrication techniques are discussed. The third part covers optical-switching fabrics, systems, and networks. Applications of optical switching in communication networks are discussed, involving optical circuit, packet, and burst switching. The chapters are self-contained with minimum overlap. They bring together academic and industrial contributions, analytical and descriptive treatments, and cover theories, experimentation, and practice. The material has been carefully coordinated to form a homogeneous manuscript having a progressive and logical development of ideas and concepts. The book embraces a number of distinctive innovations. Old and new terminologies are investigated, clarified, redefined where necessary, and used consistently throughout the entire volume. The treatment of the subject is original, not only in terms of comprehensive coverage, but also in terms of structure and organization. Twenty-four authors contributed the fourteen chapters of this book, including the Editor Tarek S. El-Bawab who authored four chapters.
