Silicon photonics is currently a very active and progressive area of research, as silicon optical circuits have emerged as the replacement technology for copper-based circuits in communication and broadband networks. The demand for ever improving communications and computing performance continues, and this in turn means that photonic circuits are finding ever increasing application areas. This text provides an important and timely overview of the ‘hot topics’ in the field, covering the various aspects of the technology that form the research area of silicon photonics. With contributions from some of the world’s leading researchers in silicon photonics, this book collates the latest advances in the technology. Silicon Photonics: the State of the Art opens with a highly informative foreword, and continues to feature: the integrated photonic circuit; silicon photonic waveguides; photonic bandgap waveguides; mechanisms for optical modulation in silicon; silicon based light sources; optical detection technologies for silicon photonics; passive silicon photonic devices; photonic and electronic integration approaches; applications in communications and sensors. Silicon Photonics: the State of the Art covers the essential elements of the entire field that is silicon photonics and is therefore an invaluable text for photonics engineers and professionals working in the fields of optical networks, optical communications, and semiconductor electronics. It is also an informative reference for graduate students studying for PhD in fibre optics, integrated optics, optical networking, microelectronics, or telecommunications.
The growing demand for instant and reliable communication means that photonic circuits are increasingly finding applications in optical communications systems. One of the prime candidates to provide satisfactory performance at low cost in the photonic circuit is silicon. Whilst silicon photonics is less well developed as compared to some other material technologies, it is poised to make a serious impact on the telecommunications industry, as well as in many other applications, as other technologies fail to meet the yield/performance/cost trade-offs. Following a sympathetic tutorial approach, this first book on silicon photonics provides a comprehensive overview of the technology. Silicon Photonics explains the concepts of the technology, taking the reader through the introductory principles, on to more complex building blocks of the optical circuit. Starting with the basics of waveguides and the properties peculiar to silicon, the book also features: Key design issues in optical circuits. Experimental methods. Evaluation techniques. Operation of waveguide based devices. Fabrication of silicon waveguide circuits. Evaluation of silicon photonic systems. Numerous worked examples, models and case studies. Silicon Photonics is an essential tool for photonics engineers and young professionals working in the optical network, optical communications and semiconductor industries. This book is also an invaluable reference and a potential main text to senior undergraduates and postgraduate students studying fibre optics, integrated optics, or optical network technology.

Many companies that stray too far from their core business fail. So how is it that General Electric, a major electrical manufacturing company, ended up as one of the top U.S. chemical producers—with 1998 sales of $6.6 billion? In Unlikely Victory, Jerome T. Coe, a retired 40-year career employee with General Electric, who spent more than 20 years as a manager of the company’s chemical businesses, suggests that it was a combination of necessity, forward-thinking of the engineers, and managers wise enough to give them breathing room. “Much of what they did (then) was counter to the prevailing GE culture,” he writes. “Today, it has become the corporate culture.” The book tells the whole story of this successful business model, from the early years of GE chemistry through the company’s successes with silicones, synthetic diamond, Lexan polycarbonate plastic, and other high-performance thermoplastics. It also profiles four scientists and five managers—including former CEO John F. Welch, Jr., a chemical engineer and a product of the GE plastic business—who made a significant difference in the company’s chemical success. The book is amply illustrated with photographs of the people, products, and plants that contributed to one of America’s most unusual corporate success stories.
Ophir Falk and Henry Morgenstern have compiled a book that should be read by anyone who is serious about winning the war on terror. By painstakingly analyzing the empirical data, they help us better understand the nature of our enemies and why they employ these barbaric tactics. Most crucially, they offer important insights on how terrorism can be effectively confronted and ultimately defeated. In so doing, they have performed an invaluable service for all those who are committed to winning this crucial battle.—Benjamin Netanyahu, Prime Minister of Israel FIRSTHAND ACCOUNTS AND ANALYSES FROM FRONTLINE PERSONNEL AND EXPERTS IN THE WAR AGAINST TERROR Based on U.S. and Israeli experiences and detailed interviews with frontline personnel, Suicide Terror enables policymakers, first responders, and students of homeland security to understand and deal with the growing threat of suicide terror. It analyzes recent suicide attacks as well as our current vulnerabilities and high-risk scenarios for future attacks. Following the expert authors' advice, readers learn possible measures to prevent an attack. Moreover, they learn how to prepare for and implement an effective and quick response to minimize casualties and losses in the event of an attack. Following an overview and historical review of suicide terror, the book covers: Global jihad Israel's confrontation with suicide terrorism America's experience with suicide bombings Internationalization of suicide terrorism High-risk scenarios and future trends Methods for confronting suicide terror Medical management of suicide terrorism Using eyewitness accounts, the text re-creates the look and feel of actual terrorism incidents. Detailed case studies help readers get into the minds of suicide terrorists in order to understand how to best prevent and confront these very dangerous threats. This book is a definitive study of suicide terror, synthesizing the experience of well-known Israeli and American experts who have dealt with it firsthand. Anyone responsible for understanding, preventing, and confronting this devastating threat should read this book and consider its recommendations with all seriousness.
