In the petroleum industry, advances in technology are required for cost-effective production
in key reservoir exploration areas and oil-well production management to increase yield and …

Sensors based on Bragg gratings inscribed in conventional single mode fibers are
expensive due to the need of a sophisticated, but low-speed, interrogation system. As an …

Optical fibers are a key component in modern photonics, where conventionally used
polymer materials are derived from fossil-based resources, causing heavy greenhouse …

We propose a directional bending sensor by mechanically bonded FBGs in a radially placed
triangular shape to measure the bending moment and its applied direction. Bending …

A compact fiber-optics sensor is proposed and demonstrated experimentally using vector
bend measurements. The device consists of a section of multiple-cladding fiber containing a …

In this Letter, we propose an in-line tilted fiber Bragg grating sensor for temperature and
strain measurements. The grating is inscribed in a specialty optical fiber using tightly …

Filament arrays were inscribed off-axis in the core of standard single-mode
telecommunication fiber, using femtosecond laser pulses. The flexible line-by-line writing …

We proposed and experimentally demonstrated an orientation-dependent fiber
displacement sensor. The sensing device consists of a simple fiber Bragg grating (FBG) …

A fiber-optic displacement sensing scheme based on high-precision detection of differential
phase is proposed, with advantages of simple structure, low cost, high precision, large …
