Arc‐induced long‐period fiber gratings accompanied with acrylate polymers coated on the silica fiber are evaluated to monitor the temperature. The transmission spectrum of the fiber grating, showing the band‐rejection filter response, is not deteriorated during the increase of the surrounding temperature up to 250°C by the advance heating–cooling process. The resonance peak wavelength shifts regularly to longer wavelength side as the temperature increased; it is approximated by a quadratic fitting curve with the coefficient of determination R 2 = 0.999. The resonance peak loss is kept at least 24 dB over the temperature measurement range. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1288–1291, 2017
