Abstract(in English) A silica fiber and long-period gratings written in it were heated to clarify the effect of the glass structure and the residual stress relaxations on resonance wavelength shifts. The change of the refractive index profile caused by heating was measured for the first time. It becomes clear that the wavelength shifts to the red side induced by heating are due to the increase of the core and the cladding indexes caused by the glass structure relaxations. We also estimated the amount of the change of the core-cladding index difference by numerical analysis. The reduction and the increase induced by heating at 600℃ for 600 hours and at 800℃ for 6 hours were estimated at -2.3x10^<-4> and +1.4x10^<-4>, respectively.
