Abstract(in English) It was shown that resonance wavelengths of long-period gratings written in silica fibers by the glass structure change were able to be adjusted by heating the whole gratings at high temperatures. However the blue shifts of the resonance wavelengths were relatively small, and the adjustable wavelength range on the short wavelength side was narrow. In this paper, long-period gratings were heated at different temperatures to investigate the heating condition for the larger blue shift of the resonance wavelengths. It has become clear that the glass structure relaxation proceeds more slowly than the residual stress relaxation with decreasing heating temperature and the effect of the residual stress relaxation appears more largely at a lower heating temperature. The resonance wavelengths can be shifted more greatly to shorter wavelengths by heating long-period gratings at a lower temperature in spite of a time-consuming process.
