“…Askins et al reported that the fiber Bragg gratings could be created in GeSiO 2 fibers by interfering beams of a single pulse of KrF laser. 33) Therefore, Figure 9 shows that the intensity of luminescence decreased to less than half upon irradiation with the KrF laser.…”

Fundamental studies of the formation of periodic structures in oxide glasses were reviewed. High spatial frequen cy gratings and twodimensional subwavelength structures were fabricated using a combination of lithography and dry etching processes. An ultrasmall demultiplexer was realized on a SiO 2 tip in which gratings, a pair of parabolic reflecting mirrors, and channel waveguides were integrated. Adopting a precisely regulated sub wavelength structure achieved low reflectance of the SiO 2 surface. Ultraviolet laser induced structural change was useful for creating diffraction functionality. The formation of point defects with intense absorption was in dispensable for inducing change of the positive refractive index of the glass. Thermally stabilized Bragg gratings and athermal waveguide filters were prepared using GeBSiO 2 glass films that were irradiated with a KrF laser.

“…On the experimental point of view, one of the difficulties for interferometry in the DUV range is due to the low coherence of available DUV lasers. As an example, typical coherence of ArF lasers is limited to a few hundreds of microns, which justifies efforts to develop specific experimental setup for short wavelengths (Figure 1 (Bourov et al, 2004), b) Lloyd setup (Raub & Brueck, 2003) and c) achromatic holographic configuration (Yen et al, 1992) Holographic grating formation has been proposed (Askins et al, 1992;Archambault et al, 1993). However, in all cases, it has been necessary to increase the spatial coherence and decrease the spectral emission band width of excimer lasers, which considerably increase the laser system complexity and demonstrations have been mostly done with 248 nm lasers.…”

“…Multiple gratings are of specific interest in sensor systems in order to allow quasi-distributed sensing and for achieving sensor multiplexing. So-called draw tower gratings, which are recorded by single pulses during the fiber drawing process, have been developed especially for this purpose [4][5][6][7]. These examples show the need for specific developments adapted to the needs of fiber sensor applications.…”

Abstract. Fiber Bragg gratings have found widespread and successful applications in optical sensor systems, e. g. for temperature, strain or refractive index measurements. Such sensor elements are fiber integrated, are applicable under harsh environmental conditions, and can be easily multiplexed. In order to further extend the field of applications, there is a great interest in specifically adapted Bragg gratings, in Bragg grating structures with increased stability, or in the use of special fiber types for grating inscription. The paper discusses such specific concepts for grating inscription, covers novel aspects of fiber gratings in small diameter fibers or in fiber tapers, of gratings in pure silica fibers without UV sensitivity, of grating inscription in different microstructured fibers or photonic crystal fibers, and investigates the concept of femtosecond inscription and the extension of the Bragg reflection wavelengths down to the visible range.
