Paper Abstract

Measurements were performed on gratings glued on different samples made of strips of commercial glass or iron. The samples were heated or cooled inside an oven or a thermo-cryostat. The Bragg wavelength shift was detected by means of an optical spectrum analyzer. The results of measurements made under different experimental conditions will be reported. These show a good linear relation between the temperature variation and the Bragg wavelength shift, but also reveal problems related to the glue hardening or to the partial ungluing of the gratings, depending on the sample material and on the glue used.
