چکیده

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.

Fabrication of fiber Bragg gratings with 267 nm femtosecond radiation.

Strong high-quality fiber Bragg gratings with photoinduced refractive-index modulation of more than 10-(3) were written in a Corning SMF-28 fiber, a P(2)O5-doped-core fiber and a pure-silica-core fluorine-doped-cladding fiber by third-harmonic radiation (267 nm, 150 fs and 1.2-1.8x1011 W/cm(2)) of a femtosecond Ti:sapphire laser using a phase mask. We compare the 267-nm photosensitivity respons...

Fabrication of corrugated Ge-doped silica fibers.

We present a method of fabricating Ge-doped SiO2 fibers with corrugations around their full circumference for a desired length in the longitudinal direction. The procedure comprises three steps: hydrogenation of Ge-doped SiO2 fibers to increase photosensitivity, recording of Bragg gratings with ultraviolet light to achieve modulation of refractive index, and chemical etching. Finite-length, rad...

Inscription of fiber Bragg gratings by ultraviolet femtosecond radiation.

We report on what is to our knowledge the first fabrication of fiber Bragg gratings by UV femtosecond radiation. The Bragg gratings, with photoinduced refractive-index modulation up to 1.92 x 10(-3) in H2-loaded SMF-28 and up to 1.05 x 10(-3) in Nufern GF1 fibers, were written by high-intensity (31-77-GW/cm2) femtosecond pulses at 264 nm. The dependence of the refractive-index modulation on int...

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.
