GNOSIS: the first instrument to use fibre Bragg gratings for OH suppression

, 2013
GNOSIS is a prototype astrophotonic instrument that utilizes OH suppression fibres consisting of fibre Bragg gratings and photonic lanterns to suppress the 103 brightest atmospheric emission doublets between 1.47-1.7 microns.

Amplification of optical delay by use of matched linearly chirped fiber Bragg gratings [PDF]

, 2004
We describe the use of a matched linearly chirped fiber Bragg grating (FBG) pair as a key element in an adjustable optical delay line. This delay line has the unique property that the achievable optical group delay is orders of magnitude greater (factor ...

Fiber Bragg Gratings with Micro‐Engineered Temperature Coefficients

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
Fiber Bragg gratings (FBGs) are intrinsically responsive to temperature and strain simultaneously. In this research, low‐loss FBGs with micro‐engineered temperature coefficients are fabricated, utilizing refractive index liquid‐filled microchannels in the cladding.

Temperature measurement of overlapped fiber Bragg grating sensors in a series fiber sensor network

Results in Optics
Fiber Bragg Gratings (FBGs) in a sensor network have been widely used for structural health and process monitoring. The number of FBGs with distinct wavelength that can be used in such a sensor network is limited by the bandwidth of the laser used. FBGs,

Simulation of Fiber Bragg Grating (FBG) as A Strain Sensor

International Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: In this study, the Fibre Bragg grating (FBG) is modelled, simulated, and characterised with respect to maximum reflectivity, bandwidth, the impact of applied strain on the wavelength shift, λB, and the wavelength shift sensitivity with strain for an optical sensing system.
