Measurement Type: Point sensing (FBG) or distributed sensing (Raman/Brillouin). Temperature Range: Ensure compatibility with high-temperature environments. Fiber optic temperature sensors are immune to the many environmental effects that compromise other measurement technologies, can be embedded and installed in locations traditional temperature sensors cannot and deliver an unprecedented level of spatial detail and data without sacrificing precision.

We demonstrate the fabrication of fiber-optic Fabry-Perot interferometer (FPI) temperature sensors by bonding a small silicon diaphragm to the tip of an optical fiber using low melting point glass powders heated by a 980 nm laser on an aerogel substrate. Besides, they exhibit high measurement speeds and high sensitivity due to the large thermal diffusivity and the large thermo-optic coefficient of silicon and the small size of the sensing element. Fiber Bragg gratings are very efficient at temperature sensing and are easy to implement; however, they always need additional techniques to discriminate the Bragg shifts by temperature and by strain/compression and they also require expensive phase-masks.
