Coupled-core optical fiber sensing
Optica Advanced Photonics Congress 2022, 2022The use of optical fibers with coupled cores is proposed for sensing applications. The interrogation of coupled-core fiber sensors is simple, fast and inexpensive as the parameter being sensed can be detected as intensity changes.

Optical Fiber Chemical Sensing Networks
SPIE Proceedings, 1987Many industrial processes or other phenomena of interest cannot be measured with conventional instruments because they are too hot, too cold, highly radioactive, or other-wise inaccessible to direct observation. Nuclear wastes stored in underground repositories, for example, will require in-situ monitoring.

Sensing with holey optical fibers
SPIE Proceedings, 2006We report our recently research on holey optical fiber sensors, including gas detection using hollow-core and solid-core silica holey fibers, two-mode holey fibers and their applications in strain and temperature measurements, long period gratings inscribed on holey fibers and their strain and temperature characteristics.

Luminescent optical fibers in sensing
1998The development of fibers doped with materials through which luminescence is generated has a long history, which follows upon the original proposal by Snitzer [1] in the early 1960s of the use of an optical fiber geometry for lasers and optical amplification, employing 300 μm core diameter neodymium doped fiber.

Principles of Optical Fiber Sensing
2017Since the Nobel Prize award in 2009, received by Prof. Charles K. Kao, for his research and pioneering achievements regarding the transmission of light in an optical fiber, optical fiber has been regarded as one of the top inventions of the last decades revolutionizing not only telecommunications systems, but also new fields of applications such as ...

Fiber-Optical 3D Shape Sensing
2014Fiber Bragg grating (FBG) technology is well known since more than three decades. It started in 1978 with the discovery of photosensitivity in optical fibers by Ken Hill et al. [1] when illuminating germanium-doped silica fibers with visible argon ion laser radiation.

SPIE Proceedings, 1988
Techniques are reviewed whereby optical fibers may be used to measure various physical parameters. Advantages and disadvantages of fiber-optic sensing are discussed. In particular, phase-modulated devices for the measurement of acceleration, rotation, acoustics, pressure, temperature, electric current, and magnetic fields are emphasized.
