This letter reports and provides an explanation for the growth behavior of long-period gratings in H/sub 2/-loaded fiber immediately after 193-nm UV inscription. Growth of grating resonance peak by as much as 14 dB was measured. Impact of temperature and grating strength, immediately after UV inscription, on the growth behavior are also discussed.
