The historical beginnings of photosensitivity and fiber Bragg grating (FBG) technology are recounted. The basic techniques for fiber grating fabrication, their characteristics, and the fundamental properties of fiber gratings are described. The many

Experimental transmission spectra of ultraviolet (u.v.)-written Bragg gratings in depressed- and matched-cladding fibre are characterized and compared. In particular, we discuss how the location and strength of the spectral features vary with the deg

We report the operation of an active, single-frequency, polarimetric, Bragg-grating fiber-laser strain sensor. The short Bragg-grating fiber-laser design limited lasing to two orthogonal polarization modes that, when optically mixed, yielded a single

Bragg gratings have been produced in germanosilicate optical fibers by exposing the core, through the side of the cladding, to a coherent UV two-beam interference pattern with a wavelength selected to lie in the oxygen-vacancy defect band of germania

The temperature and strain response of fiber grating sensors can be isolated using single or multiple gratings. The necessary diversity in the measurement can be achieved by using special coatings or dual-mode techniques. Analytical and experimental

Each discrete complex wave supported by a uniaxial layer corresponds to an isolated singularity in an appropriate Green's function. The location of a singularity depends on the geometry, plasma density, and the direction of the magnetic field, but no

Experimental transmission spectra of UV-written Bragg gratings in depressed-cladding fibre are characterised. The fine-structure features on the short-wavelength side of the fundamental Bragg line are shown to be due to coupling between the LP01 and

Additional grating resonances are observed near the fundamental-mode Bragg wavelength in depressed-cladding fibre. They occur above and below the LP/sub 11/ cutoff. Images of the reflected and transmitted fields and calculations of the phase-matching

This paper will describe a polarimetric fiber laser sensor which utilises intra core Bragg gratings to limit laser modes to two and for laser wavelength predetermination. >
