Enhanced Optical Fiber Lasers and Optical Fiber Sensors Assisted by Micro-drilled Optical Fibers

open access: yesOptical Fiber Sensors Conference 2020 Special Edition, 2021
Enhanced OFS assisted by micro-drilled optical fibers acting as mirrors are demonstrated. Strain sensitivity improved more than one order of magnitude in comparison with FBG sensors using a 50 μm-waist micro-drilled taper as distributed reflector.

Microbend fiber-optic sensor [PDF]

open access: yesApplied Optics, 1984
Intensity modulation induced by microbending in multimode fibers is considered as a transduction mechanism for detecting environmental changes such as pressure, temperature, acceleration, and magnetic and electric fields. A generic microbend sensor has been defined and studied, and its components, such as sensing fiber, light source, optical fiber ...
