Introduction to Fiber Optics

Recent advances in the development of low-loss optical fibers have revolutionized the field of telecommunications, and fiber-based networks form a key part of international communications systems. This book introduces the physical principles of optical fibers, and details their use in sensor technology and modern optical communication systems. The authors begin by setting out the basic propagation characteristics of single mode and multimode optical fibers. In later chapters they cover optical sources, optical detectors, and fiber-optic communication system design. They also treat a wide variety of related topics such as doped fiber amplifiers, dispersion compensation, fiber sensors, and measurement techniques for the characterization of optical fibers. The book emphasizes physical and engineering aspects of the subject. It will be an ideal textbook for undergraduate or graduate students taking courses in optical fiber communications, photonics, or optoelectronics.

Recent earthquakes and space program-related news serve as potent reminders of the uses fiber optic technology offers to an increasingly complex world. Like living organisms sensitive to subtle changes in the environment, buildings, structures, and space vehicles can be equipped to sense and react to their surroundings by means of hair-thin glass fiber sensors embedded in structural materials and capable of carrying information and measuring changes in stress and other environmental factors. Data is collected and transmitted to a central location, where the findings are assessed and damage corrected. Fiber Optic Smart Structures pools the expertise of thirty-three leading professionals, many of whom are pioneers in the field, and offers a comprehensive introduction to this fast growing technology. Beginning with a historical overview and a look at the background technology, the book goes on to discuss methods of embedding optical fibers in modern high-strength, lightweight composite materials; ingress and egress of optical fibers; and more specialized application concerns, including use of the Fabry-Perot interferometer and Bragg grating sensors. Lower cost options are considered in light of performance trade-offs, and broad area coverage through single-line stringing of multiple fiber sensors is compared with single and distributed sensor approaches. The last section of the book treats the use of fiber optic smart structures in a wide range of settings. Discussions include applications in environments where high temperature and ultrasonic waves play a role; in the aerospace industry, where changes in the structural integrity of the system demand real-time automatic changes; and arapidly emerging new direction, earthquake-resistant buildings and, along similar lines, bridges that perform self-diagnostics.

Doubly clad fiber - In fiber optics, a doubly clad fiber is a single-mode optical fiber that has two claddings. This is also called depressed-inner-cladding fiber, and W-profile fiber (from the fact that a symmetrical plot of its refractive index profile superficially resembles the letter W).

Polarization-maintaining optical fiber - In fiber optics, a polarization-maintaining optical fiber (PM) is an optical fiber in which the polarization planes of lightwaves launched into the fiber are maintained during propagation with little or no cross-coupling of optical power between the polarization modes. There are several different designs with slightly different characteristics.

Quadruply clad fiber - In fiber optics, a quadruply clad fiber is a single-mode optical fiber that has four claddings. Each cladding has a refractive index lower than that of the core.

Optical fiber - An optical fiber (or fibre) is a transparent thin fiber, usually made of glass or plastic, for transmitting light. Fiber optics is the branch of science and engineering concerned with such optical fibers.

Johnson (1989). He also proposed the idea of a few rivers including the River Severn. In 2001, the practical use of solitons became a reality when Algety Telecom deployed submarine telecommunications equipment in Europe carrying real traffic using John Scott Russell's solitary wave. Pump lasers, coupled to the optical amplifiers, activate the erbium, which energizes the light pulses. See also Soliton (topological).
