High-speed interferometric FBG interrogator with dynamic and absolute wavelength measurement capability [PDF]

open access: yes, 2013
A passive, interferometric wavelength demodulation technique has been extended to measure the absolute wavelengths of a multiplexed array of fiber Bragg grating sensors. The scheme retains its original strain resolution of 10 nε/√{Hz}. A proof-of-concept

X-ray Writing of Fiber Bragg Gratings (FBGs)

open access: yes, 2020
Fabrication of nanoscale optical Fiber Bragg Gratings (FBGs) is one of the key manufacturing processes for fiber optics, which has many important applications in data communication and distributed remote sensing at a distance up to hundreds of kms. However, the fabrication of the FBGs is challenging.

Tunable Random Fiber Laser Based on Dual-Grating Structure

open access: yesPhotonics, 2023
In order to reduce the pumping threshold and achieve a short-cavity single-mode transmission with a narrow-linewidth random fiber laser, we propose a tunable random fiber laser based on the combination of random grating and highly reflective fiber Bragg ...

Klein tunneling of light in fiber Bragg gratings [PDF]

open access: yes, 2010
A photonic analogue of Klein tunneling (KT), i.e. of the exotic property of relativistic electrons to pass a large repulsive and sharp potential step, is proposed for pulse propagation in a nonuniform fiber Bragg grating with an embedded chirped region ...
