Interrogation of fibre Bragg gratings with a tilted fibre Bragg grating

Measurement Science and Technology, 2004
A new and efficient interrogation scheme suitable for monitoring the Bragg wavelengths of multiplexed fibre Bragg gratings is presented. The heart of the technique consists of a tilted and chirped fibre Bragg grating placed in front of a photodetector linear array.

A fibre Bragg grating refractometer

Measurement Science and Technology, 2001
An opto-chemical in-fibre Bragg grating (FBG) sensor for refractive index measurement in liquids has been developed using fibre side-polishing technology. At a polished site where the fibre cladding has partly been removed, a FBG is exposed to a liquid analyte via evanescent field interaction of the guided fibre mode. The Bragg wavelength of the FBG is

Modulational instability in a fibre and a fibre Bragg grating

Journal of Optics B: Quantum and Semiclassical Optics, 2004
In this review article, we study the influence of cross-phase modulation, higher order nonlinear effects such as self-steepening, self-induced Raman scattering and higher order dispersion effects such as third and fourth order dispersion on cross-phase modulational instability for a highly elliptical birefringent optical fibre, and obtain the ...

Fibre Bragg gratings for temporal spectral astronomy

SPIE Proceedings, 2010
Temporal spectral astronomy or time resolved astronomy is the study of astrophysical phenomena that show spectral variability on very short timescales. These timescales are often too short to be resolved by current astronomical equipment. The lack of detailed observations in this area keeps important theoretical descriptions of astronomical events ...
