“…Later, spectrum-based sensing methods were studied in search of higher accuracy. Several sensing schemes have been proposed and demonstrated in the past few decades to fabricate temperature sensors, including wafer- [3] and air gap-based [4,5] Fabry-Perot interferometers (FPIs) and fiber Bragg gratings [6]. Most reported spectrum-based sensing schemes rely on sensors that must be individually fabricated and tested, making them less viable for mass production.…”

“…Most reported spectrum-based sensing schemes rely on sensors that must be individually fabricated and tested, making them less viable for mass production. The sapphire fiber Bragg gratings-based temperature sensor reported in [6] is batch-fabrication ready, but it requires careful control of the modal excitation condition into the sapphire fiber because a single-mode outputting tunable laser was used to interrogate the Bragg gratings. If many modes are excited in the sapphire fiber, the reflection spectrum from the gratings will be smeared such that the performance of the sensor is greatly compromised.…”

A submicrometer-thick zirconium dioxide film was deposited on the tip of a polished C-plane sapphire fiber to fabricate a temperature sensor that can work to an extended temperature range. Zirconium dioxide was selected as the thin film material to fabricate the temperature sensor because it has relatively close thermal expansion to that of sapphire, but more importantly it does not react appreciably with sapphire up to 1800°C. In order to study the properties of the deposited thin film, ZrO 2 was also deposited on C-plane sapphire substrates and characterized by x-ray diffraction for phase analysis as well as by atomic force microscopy for analysis of surface morphology. Using low-coherence optical interferometry, the fabricated thin-film-based sapphire fiber sensor was tested in the lab up to 1200°C and calibrated from 200°to 1000°C. The temperature resolution is determined to be 5.8°C when using an Ocean Optics USB4000 spectrometer to detect the reflection spectra from the ZrO 2 thin-film temperature sensor.

“…Mihailov [11] used femtosecond laser to write a FBG on a common single mode fiber by phase mask plate method. In order to further enhance the high temperature characteristic of type II fiber grating, Grobnic [12] made normal working temperature at 1500℃ of type II fiber grating successfully, and its highest working temperature up to 2000℃. However, long time required for production of laser exposure and it is too difficult to mass production.…”

“…Because of their immunity to electromagnetic interference and possibility to work in contact with explosives, the use of optical fibers for temperature monitoring has been widely investigated [1][2][3][4]. Among optical fiber devices, fiber Bragg gratings (FBGs) [1,[5][6][7][8][9][10][11][12] are possibly the most common tool used for temperature sensing. FBGs inscribed in telecom optical fibers can reach temperatures T as high as 800 o C [8].…”
