Over the last two decades UV-induced Δn profiling in SiO2 glasses was widely used for
production of in-fibre/waveguide Bragg grating-based (BG) optical devices for photonics …

Although mainstream grating writing, more often than not using single photon excitation of
germanosilicate based defects with CW 244 nm light, remains the key technology for …

Experimental results and a discussion of possible chemical pathways in the formation of
thermally stable chemical composition gratings in optical fibers are presented. Gratings are …

Strong grating formation in pure silica-core fibers by use of 193-nm ArF-laser radiation is
reported. Unsaturated refractive-index changes of Δn∼ 0.3× 10^-3 were observed in …

Phosphosilicate fibre gratings can be stabilized at temperatures in excess of 500 C for
sensor applications by optimizing thermal and UV presensitization recipes. Furthermore, the …

Recent advances within the realization of silica-based planar waveguide circuitry are
presented. This ranges from the production methods for planar waveguides, including a …

This paper reviews both recent progress in enhanced photosensitivity and in thermal poling.
It is shown that, whereas recent research on photosensitivity focuses on specific issues …

We present the first demonstration of integrated waveguides in planar silica devices
fabricated using direct UV writing with 213 nm laser light. Waveguides were produced with …

In this work, we have demonstrated for the first time grating regeneration in hydrogenated
fibers by direct CO_2 laser annealing. During the annealing process, the center wavelength …
