Abstract With the development of low loss single mode optical fiber waveguides, it is possible to construct a gyroscope using optical fibers. The configuration is a multi-turn Sagnac interferometer. Light from an external source is split and injected into the fiber ends, travels in clockwise and counterclockwise directions and is recombined to form ...

Annual Review of Earth and Planetary Sciences, 2021
Distributed acoustic sensing (DAS) is an emerging technology that repurposes a fiber-optic cable as a dense array of strain sensors. This technology repeatedly pings a fiber with laser pulses, measuring optical phase changes in Rayleigh backscattered light.

Optical fibers for communication
IEEE Journal of Quantum Electronics, 1973The transparency of glass fibers in the visible and near infrared-improved beyond all expectations by recent breakthroughs-seems now sufficient to transmit optical signals unprocessed over miles. No wonder that efforts have intensified all over the world to utilize fibers in future communication systems.

Proceedings of the International Conference and Workshop on Emerging Trends in Technology, 2010
This paper deals with the analysis of the current POF market trends and its estimated growth in the vital sectors in the years to come. Plastic optical fibers have now come into the limelight since they have become an apparent middle ground between copper and glass optical fibers.

Optical fibers for optical networking
Bell Labs Technical Journal, 2002This paper describes the influence of optical networking on the design of optical fibers. It reviews fundamental optical properties, describes the various fiber types, discusses the fiber requirements for optical networking, and considers the effects of fiber nonlinearities. Finally, the paper describes three new optical fibers from Lucent Technologies

SPIE Proceedings, 1984
The engeneerized prototipe of a fiber-optic sensor useful for vibration measurement in hostile environments is presented.The vibrometer is essentially based on a "differential" heterodyne Michelson-type interferometer in which the reference beam and the sensing beam are both guided, with orthogonal polarization, by the same single-mode polarization ...

Optical fibers and their applications
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract Fiber optics have become in the last few years an extremely attractive method of data transfer. A short review of their properties and of their applications is given, together with some feelings from personal experience of the author.
