Paper Abstract

We report for the first time the refractive index grating side-writing in 10 mol.% GeO2-doped fiber by near-UV light of cw Ar+-laser (333 - 364 nm). The magnitude of induced index change as large as 1.9 multiplied by 10-4 at 1.7 multiplied by 105 W/cm2 UV power density has been achieved. The observed gratings have exhibited the same temperature stability as gratings written by KrF excimer laser (248 nm).
