High intensity ArF laser irradiation produces Bragg gratings with inde
x modulations > 10(-3) in standard germanium-doped silica waveguides w
ithout hydrogen loading. A UV-induced birefringence of 2 x 10(-4) is u
sed to compensate for the inherent birefringence of the silica wavegui
des and makes the grating response identical for TE and TM modes.
