2008 10th Anniversary International Conference on Transparent Optical Networks, 2008
We give fiber or planar lightwave circuit (PLC) architectures to implement the discrete Fourier transform (DFT) and the discrete Hartley transform (DHT) directly in the optical domain. In both cases, we present a recursive approach for the decimation-in-frequency algorithm, considering parallel and serial input configurations.

Hollow Core DNANF Optical Fiber with <0.11 dB/km Loss
Optical Fiber Communications Conference and ExhibitionWe report the fabrication of a hollow-core DNANF with a geometry extensively optimized for minimum loss. Three independent loss measurements average 0.08±0.03 dB/km at 1550 nm, the lowest attenuation ever achieved in an optical fiber.

A Comprehensive Review of Optical Fiber Refractometers: Toward a Standard Comparative Criterion
Laser & Photonics reviews, 2019Thanks to the peculiarities of optical fiber and its ability to be combined with nanotechnology, precise and accurate measurements of the changes in optical properties (i.e., refractive index) of the medium surrounding the fiber are becoming possible ...

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.

Publisher Summary This chapter focuses on silica-based optical fibers, which are the most important transmission media for long-distance and large-capacity optical communication systems. A distinguishing feature of these optical fibers is their low loss characteristics.

IFAC Proceedings Volumes, 1979
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 ...

Optical Fibers for Fiber Optic Gyroscopes
2019With the possible exception of nonsilica glasses, each time a new fiber technology has emerged, someone has applied it to FOGs and reported beneficial results. The development of the FOG has essentially tracked that of commercial optical fibers for more than 40 years, running parallel since 1976, when Vali and Shorthill first demonstrated the concepts ...
