All optical networks offer new possibilities for high bandwidth applications. New techniques are demonstrated for optical switching and network management for complex optical networks. WDM systems allow upgrading of the backbone optical network. This work explores the current state of research and future developments of optical network technology and applications. Photonic networks are discussed from a variety of viewpoints, including network analysis, modelling and simulation, active and passive devices, as well as packaging.
The day when fiber will deliver new, yet now only foreseeable, broadband ser vices to the end user is getting nearer and nearer as we make our way towards the prophetic year 2000. Step by step, as we move from first generation lasers and fibers to the by now common erbium-doped fiber amplifiers, looking forward to such things as wavelength multiplexing and solitons, photonic switching and optical storage, the community of researchers in optical communications has stepped into the era of photonic networks. It is not just a question of terminology. Optical communication means tech nology to the same extent that photonic network means services. If it is true that information is just as marketable a product as oil or coke, the providing of an extensive global information infrastructure may end up having an even greater impact than the setting up of a world-wide railroad network did at the beginning of the industrial era. Just like wagons, bandwidth will be responsible for carrying and delivering goods to customers. The challenge for all of us in this field is for it to function in every section of the overall network, transport, access and customer area, in the best possible way: the fastest, most economical and most flexible. New services provided by a new network that exploits the potential and peculiarities of photonics surely requires a rethinking of solutions, new ideas, new architec tures, new design, especially where electronics is still dominant, as in transport and access networks.
PATTERNS ACROSS CULTURES is a rhetorically organized reader driven by the principle that as the world gets smaller, students should be exposed to a wide variety of cultural perspectives--both from within the United States and from other countries. Many of the reading selections in the text are by writers who have never been anthologized, providing an invigorating alternative to traditional readers. Post-reading features for each selection, including questions on author's "Meaning," "Technique," and "Language," help students examine how the selection utilizes both the primary mode and other modes as well; calls out key vocabulary terms; highlights thematic connections between selections; and provides prompts for both personal and critical writing. To assist those instructors who prefer a thematic framework for discussing the selections, a thematic Table of Contents and Thematic Links questions connecting each essay with one or more others on similar themes will provide inspiration for theme-based discussions and writing assignments.

Optics and photonics technologies are ubiquitous: they are responsible for the displays on smart phones and computing devices, optical fiber that carries the information in the internet, advanced precision manufacturing, enhanced defense capabilities, and a plethora of medical diagnostics tools. The opportunities arising from optics and photonics offer the potential for even greater societal impact in the next few decades, including solar power generation and new efficient lighting that could transform the nation's energy landscape and new optical capabilities that will be essential to support the continued exponential growth of the Internet. As described in the National Research Council report Optics and Photonics: Essential Technologies for our Nation, it is critical for the United States to take advantage of these emerging optical technologies for creating new industries and generating job growth. The report assesses the current state of optical science and engineering in the United States and abroad-including market trends, workforce needs, and the impact of photonics on the national economy. It identifies the technological opportunities that have arisen from recent advances in, and applications of, optical science and engineering. The report also calls for improved management of U.S. public and private research and development resources, emphasizing the need for public policy that encourages adoption of a portfolio approach to investing in the wide and diverse opportunities now available within photonics. Optics and Photonics: Essential Technologies for our Nation is a useful overview not only for policymakers, such as decision-makers at relevant Federal agencies on the current state of optics and photonics research and applications but also for individuals seeking a broad understanding of the fields of optics and photonics in many arenas.
