The Use of Fibre Bragg Grating To Monitor the Early Age Curing Temperature of Cement Paste
Electronic Journal of Structural Engineering, 2013 In this paper, a Fibre Bragg Grating (FBG) is used to monitor the early age curing temperature of cement paste. The FBG is inscribed by a Continuous Wave (CW) 244nm argon ion laser in the photosensitive fibre.

Rapid characterization of the ultraviolet induced fiber Bragg grating complex coupling coefficient as a function of irradiance and exposure time [PDF]
, 2007 We report the application of optical frequency domain reflectometry and a discrete-layer-peeling inverse scattering algorithm to the spatial characterization of the UV induced complex coupling coefficient during fiber Bragg grating growth.

Advanced Energy and Sustainability Research, EarlyView.Efficient water electrolysis in NaBr electrolyte is achieved using TiO2 nanotube supports decorated with Ru nanoparticles. A cooperative “job‐sharing” effect between the TiO2 proton‐storage support that provides protons to the Ru catalyst enhances hydrogen evolution, minimizes Ru demand and polarization losses, and delivers stable performance ...

Acousto-optic superlattice modulator using Fibre Bragg grating
, 1997 A modulator is reported in which an extensional acoustic wave is launched along a fiber Bragg grating. The acousto-optic superlattice effect causes an enhancement in reflectivity within a narrow spectral region on both sides of the Bragg wavelength.
