Photosensitisation of Phosphosilicate Fibre Bragg Gratings

Photosensitivity and Quadratic Nonlinearity in Glass Waveguides: Fundamentals and Applications, 1995
Photolytic grating writing in phosphorous doped waveguides has recently been possible only with substantial hydrogen loading [1-3]. In [1] this has been demonstrated for phosphosilicate planar waveguides using 193nm whilst for aluminophosphosilicate fibres the writing wavelength was the 248nm KrF line [2]. We have recently demonstrated photosensitivity

Packaging of optical Fibre Bragg Gratings

2001 Proceedings. 51st Electronic Components and Technology Conference (Cat. No.01CH37220), 2002
Fibre Bragg Gratings (FBGs) are all-fibre optical filters with applications in sensing and telecommunication systems. The packaging of FBGs offers many challenges to the manufacturer as stringent tolerances for wavelength stability of the filter over widely varying environmental operating conditions are required for state of the art Dense Wavelength ...

Dynamic studies of fibre Bragg gratings

SPIE Proceedings, 2010
The dynamic performance of standard fibre Bragg gratings (FBGs) is assessed. The interrogating system used for all the reported measurements was an all fibre optic Mach Zehnder interferometer which generated a fade free optical carrier to enable heterodyne processing to be exploited.

Thermal decay of fibre Bragg gratings

11th International Conference on Integrated Optics and Optical Fibre Communications. 23rd European Conference on Optical Communications IOOC-ECOC97, 1997
The thermal decay of fibre Bragg gratings is examined over a period in excess of 5000 hours. A new model is presented to predict the decay characteristics of gratings written in hydrogen loaded fibre.

Fibre Bragg Grating Components (WG4)

1999
The COST 246 Working group WG4 “Bragg grating components” investigated the reliability of a new kind of all-fibre devices based in the coupling of different fibre modes by UV laser fabricated phrase gratings. The most prominent phase grating that couples the forward propagating to the backward propagating fundamental mode is called the fibre Bragg ...
