Abstract

Fibre Bragg gratings (FBGs) have found extensive application in lasers, amplifiers, signal filtering in telecommunications and sensing. The underlying mechanisms and fundamental properties of FBGs are not completely understood, which stands in the way of full exploitation of FBG-based devices across a range of technologies. Differential Interference Contrast (DIC) microscopy was used in this thesis to investigate the internal refractive index structures of FBGs fabricated using various techniques. By measuring the light transmitted through FBGs at various wavelengths, the information gained from spectral measurements has been compared with the DIC images. The sensing capacities of complex structure FBGs were investigated using standard sensor calibration techniques which monitor wavelength shifts with changes in temperature and strain.
