Abstract

The effect of hydrogen loading on near-UV photosensitivity of germanosilicate glass is studied. The enhanced bleaching of 390 nm luminescence band and 240 nm absorption band, as well as enhanced growth of 650 nm luminescence band in hydrogen loaded samples is observed. The increase of paramagnetic GeE' defects concentration and creation of hydrogen related paramagnetic H(II) centers is obtained. Long period index gratings with low insertion loss and index change as large as 4 multiplied by 10^-4 are fabricated by near-UV argon laser radiation in hydrogen loaded fibers. The effect of gamma irradiation on the properties of the fabricated gratings is reported.
