Abstract
This is the first report, to our knowledge, of refractive-index gratin g side writing in 10 mel. % GeO2-doped fiber by the near-UV Light of a cw Ar+ laser (333-364 nm). An induced-index magnitude as large as 1.9 x 10(-4) at 1.7 x 10(5) W/cm(2) UV power density has been achieved. T he observed gratings have exhibited the same temperature stability as gratings written by a KrF excimer laser (248 nm). (C) 1997 Optical Soc iety of America.
