Optical science and engineering affect almost every aspect of our lives. Millions of miles of optical fiber carry voice and data signals around the world. Lasers are used in surgery of the retina, kidneys, and heart. New high-efficiency light sources promise dramatic reductions in electricity consumption. Night-vision equipment and satellite surveillance are changing how wars are fought. Industry uses optical methods in everything from the production of computer chips to the construction of tunnels. Harnessing Light surveys this multitude of applications, as well as the status of the optics industry and of research and education in optics, and identifies actions that could enhance the field's contributions to society and facilitate its continued technical development.

Photonic devices lie at the heart of the communications revolution, and have become a large and important part of the electronic engineering field, so much so that many colleges now treat this as a subject in its own right. With this in mind, the author has put together a unique textbook covering every major photonic device, and striking a careful balance between theoretical and practical concepts. The book assumes a basic knowledge of optics, semiconductors and electromagnetic waves. Many of the key background concepts are reviewed in the first chapter. Devices covered include optical fibers, couplers, electro-optic devices, magneto-optic devices, lasers and photodetectors. Problems are included at the end of each chapter and a solutions set is available. The book is ideal for senior undergraduate and graduate courses, but being device driven it is also an excellent engineers' reference.

In 1969, Senator John Pastore requested that the Surgeon General appoint a committee to conduct an inquiry into television violence and its effect on children. When the Surgeon General's report was finally released in 1972—after a three-year inquiry and a cost of over $1.8 million—it angered and confused a number of critics, including politicians, the broadcast industry, many of the social scientists who had helped carry out the research, and the public. While the final consequences of the Report may not be played out for years to come, TV Violence and the Child presents a fascinating study of the Surgeon General's quest and, in effect, the process by which social science is recruited and its findings made relevant to public policy. In addition to dealing with television as an object of concern, the authors also consider the government's effectiveness when dealing with social objectives and the influence of citizen action on our communication systems. Their overwhelming conclusion is that the nation's institutions are ill-equipped for recruiting expert talent, providing clear findings, and carrying out objectives in this area of delicate human concern.
