Abstract (EN): A fiber optic sensor for high sensitivity refractive index and temperature measurement able to withstand temperature up to 450 degrees C is reported. Two identical LPG gratings were fabricated, whereas one was coated with a high refractive index (similar to 1.78) sol-gel thin film in order to increase its sensitivity to the external refractive index. The two sensors were characterized and compared in refractive index and temperature. Sensitivities of 1063 nm/RIU (1.338 - 1.348) and 260 pm/degrees C were achieved for refractive index and temperature, respectively.
