Photonics in Switching provides a broad, balanced overview of the use of optics or photonics in switching, from materials and devices to system architecture. The chapters, each written by an expert in the field, survey the key technologies, setting them in context and highlighting their benefits and possible applications. This book is a valuable resource for those working in the communications industry, either at the professional or student level, who do not have extensive background knowledge or the underlying physics of the technology.
Directed toward physicists and engineers interested in the device applications enabled by nonlinear optics, this text is suitable for advanced undergraduates and graduate students. Its content is presented entirely on a classical basis and requires only an elementary knowledge of quantum mechanics. The authors demonstrate how real laboratory situations can diverge from ideal theory, acquainting readers with the kinds of problems common to construction of a nonlinear device. They also offer a detailed discussion of the practical problems and characteristics of nonlinear materials, as well as the selection procedures necessary to ensure the use of good material. Their treatment begins with an introduction to the theories of linear and nonlinear optics, along with the basic ideas behind them. Succeeding chapters explore phase matching and nonlinear materials, followed by detailed treatments of second-harmonic generation, parametric up-conversion, and optical parametric amplification and oscillation. Appendixes offer a comprehensive list of materials and their properties; the text concludes with references and an index.
This compact and accessible reference work provides all the essential facts and figures about major aspects of modern British history from the death of Queen Anne to the end of the 1990s. The Longman Handbook of Modern British History has been extended to include a fully-revised bibliography (reflecting the wealth of newly published material in recent years), the new statistics on social and economic history and an expanded glossary of terms. The political chronologies have been revised to include the electoral defeat of John Major and the record of New Labour in office. Designed for the student and general reader, this highly-successful handbook provides a wealth of varied data within the confines of a single volume.
Biblical scholars today often sound as if they are caught in the aftermath of Babel -- a clamor of voices unable to reach common agreement. Yet is this confusion necessarily a bad thing? Many postmodern critics see the recent profusion of critical approaches as a welcome opportunity for the emergence of diverse new techniques. In The Bible after Babel noted biblical scholar John J. Collins considers the effect of the postmodern situation on biblical, primarily Old Testament, criticism over the last three decades. Engaging and even-handed, Collins examines the quest of historical criticism to objectively establish a text's basic meaning. Accepting that the Bible may no longer provide secure "foundations" for faith, Collins still highlights its ethical challenge to be concerned for "the other" -- a challenge central both to Old Testament ethics and to the teaching of Jesus.
