Grating formation in pure silica-core fibers

Abstract

Strong grating formation in pure silica-core fibers by use of 193-nm ArF-laser radiation is reported. Unsaturated refractive-index changes of $\mathrm{\Delta }n\sim 0.3\times {10}^{-3}$ were observed in nontreated fiber, and changes of $\mathrm{\Delta }n\sim 0.5\times {10}^{-3}$ were observed in fibers with a high hydroxyl concentration. Possible mechanisms of photosensitivity in pure silica-core fibers are discussed.
