Hardback. Etat : Good. Fiber optic technology is revolutionizing telecommunications and thus our lives. Networks of opitcal fibers have spread around the world, opening the door to the possibility of a new information age, and spurring telephone and cable television companies into a billion-dollar race for control over the next generation of services and equipment. The story of this technology is fascinating complex, and largely untold. Hecht tells this story, from its beginning in 19th-century attempts to guide light, for purposes of illuminating the insides of the human body, to today's mysterious, ubiquitous communications technologies. We hear the crucial conversation in 1951 that led to the realization that optical fibers might conduct light if coated with a layer of transparent material. Hecht also describes the medical technologies developed in the 1960's, which allowed doctors to see inside patients' stomachs and better understand gastric disorders. And we learn of the race to develop fiber-optic technology that could control the laser, the brilliant concentrated beam that captured the imagination of the physics community. This history is meticulously detailed from beginning to end, allowing for explorations of experiments that now seem strange and even humorous, but nonetheless illuminate the origins of the technology. We get the whole story, including the huge range of contributing characters, accidents, and revolutionary ideas. The book is infused with the spirit of fascination and fun, and the reader will enjoy the story for its own sake, as well for the historical picture it provides of a technology on which we all depend.…

Paperback. Etat : Good. City of Light tells the story of fiber optics, tracing its transformation from 19th-century parlor trick into the foundation of our global communications network. Written for a broad audience by a journalist who has covered the field for twenty years, the book is a lively account of both the people and the ideas behind this revolutionary technology. The basic concept underlying fiber optics was first explored in the 1840s when researchers used jets of water to guide light in laboratory demonstrations. The idea caught the public eye decades later when it was used to create stunning illuminated fountains at many of the great Victorian exhibitions. The modern version of fiber optics--using flexible glass fibers to transmit light--was discovered independently five times through the first half of the century, and one of its first key applications was the endoscope, which for the first time allowed physicians to look inside the body without surgery. Endoscopes became practical in 1956 when a college undergraduate discovered how to make solid glass fibers with a glass cladding. With the invention of the laser, researchers grew interested in optical communications. While Bell Labs and others tried to send laser beams through the atmosphere or hollow light pipes, a small group at Standard Telecommunication Laboratories looked at guiding light by transparent fibers. Led by Charles K. Kao, they proposed the idea of fiber-optic communications and demonstrated that contrary to what many researchers thought glass could be made clear enough to transmit light over great distances. Following these ideas, Corning Glass Works developed the first low-loss glass fibers in 1970. From this point fiber-optic communications developed rapidly. The first experimental phone links were tested on live telephone traffic in 1977 and within half a dozen years long-distance companies were laying fiber cables for their national backbone systems. In 1988, the first transatlantic fiber-optic cable connected Europe with North America, and now fiber optics are the key element in global communications. The story continues today as fiber optics spread through the communication grid that connects homes and offices, creating huge information pipelines and replacing copper wires. The book concludes with a look at some of the exciting potential developments of this technology.…
