This paper reports and provides an explanation for the growth behavior of long-period gratings in H2-loaded fiber immediately after 193nm 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.
