Contribution of photoinduced densification to refractive-index modulation in Bragg gratings written in Ge-doped silica fibers.

We have computed the contribution of UV-light-induced densification to the refractive-index modulation of fiber Bragg gratings. Our results confirm that, for strong gratings written in Ge-doped silica fibers with 248-nm UV light, density changes account for a major part of the photosensitivity effect.

Photosensitivity in tin-doped silica optical fibres

Permanent gratings (refractive index modulation ~3x10 ) were written in tin-doped silica -4 optical fibres with low levels of SnO (~0.15 mol %). In Ge-doped silica, ~10 mol% GeO is 2 2 required to produce comparable photorefractivity under similar conditions. Photosensitivity in tin-doped silica optical fibres G. Brambilla, V. Pruneri, L.

Properties of SnS thin films grown by physical vapour deposition

Thin films of tin sulfide (SnS) were prepared by thermal evaporation technique on glass substrates and on n-type Si substrate and their physical properties were studied. The phase of the obtained thin films before and after thermal treatment was confirmed by X-ray diffraction analysis and Raman spectra. Optical transmission and reflection spectra were measured in the wavelength range 300-1800 n...

Photosensitivity in Ge-doped silica optical waveguides and fibers with 193-nm light from an ArF excimer laser.

Photosensitivity in optical fibers and waveguides has been associated with the bleaching of an absorption band located near 5.0 eV (or 242 nm). We present new results for Bragg grating formation and UV bleaching experiments carried out using 193-nm light from an ArF excimer laser instead of the usual laser sources operating near 242 or 248 nm.
