چکیده انگلیسی
A novel fabrication method for thermal regenerated fiber Bragg grating (RFBG) with intensity larger than 43% (reflective to the original FBG) was developed. Conventional seed fiber Bragg grating (SFBG) was erased at 800â¯Â°C. The sample was continuously heated to 900â¯Â°C, during which RFBG occurred. The as-prepared RFBG was taken for thermal annealing cycles (18â¯Â°C-1000â¯Â°C) to study its wavelength shift characteristics. At the beginning of the test, the wavelength was unstable and inclined to increase 148â¯pm. After four cycles, the wavelength reached a stable value. Temperature sensing experiment at 18â¯Â°C-1000â¯Â°C was carried out for RFBG and a sensitivity of (11.07â¯+â¯0.00781T)â¯pm/°C with a satisfactory stability was obtained. The developed RFBG could be applied to high temperature detection in aerospace industries.
