“…However, it is possible to coat PCFs with polymers that have higher operating temperature range. Some acrylates, silicone, or polyimide, for example, can resist temperatures up to 150 or 400°C [19]- [21], and gold coatings can withstand temperatures up to 800°C [22]. The protecting coating of the PCF does not affect the interfering modes neither the fringe contrast of the interferometer.…”

A compellingly simple force sensor based on a photonic crystal fiber (PCF) mode interferometer is presented. A mechanical piece with grooves is used to convert the external force in localized pressure on the sensitive part of the interferometer. The localized pressure on the PCF causes attenuation losses to the interfering modes and makes the interference pattern to shrink. The changes of the interference pattern are quantified by means of Fourier transformation. In the sensing architecture here proposed, temperature or power fluctuations of the light source do not affect the measurement.Index Terms-Photonic crystal fiber interferometers, optical fiber sensors, mode interferometers, force sensor, pressure sensor.

“…Copper does not react with silica at high temperatures and it has a higher melting point than aluminum (approximately 1000 °C), which makes it a better option for high temperature applications [22]. However, the oxidation process on the copper surface in the presence of oxygen at high temperatures causes a deterioration of the mechanical properties of copper coated fibers [23].…”

An experimental study of a high temperature distributed optical fiber sensor based on Raman Optical-Time-Domain-Reflectometry (ROTDR) (up to 450 °C) and optical fibers with different coatings (polyimide/carbon, copper, aluminum and gold) is presented. Analysis of the distributed temperature sensor (DTS) measurements determined the most appropriate optical fiber to be used in high temperature industrial environment over long periods of time. To demonstrate the feasibility of this DTS for an industrial application, an optical cable was designed with the appropriate optical fiber and it was hermetically sealed to provide the required mechanical resistance and isolate the fiber from environmental degradations. This cable was used to measure temperature up to 360 °C of an industrial furnace during 7 days.
