“…Based on the measurements carried out with an OSA presented in Figure 5, an effective operational spectral range of an interrogator is equal to circa 10 nm. Based on Equations ( 2) and ( 4) and parameters from Figure 3, for such a wavelength span, the temperature can be measured in the range of up to 760 • C. However, for some applications, such as power plant monitoring [53,54], or turbine engine examination [18,55,56], a much larger temperature range is required. To overcome such a limitation, one can either use two or more VCSELs in the interrogator unit or extend wavelength sweeping range through either a temperature or current manipulation.…”

“…However, with the utilization of specialized optical fiber Bragg gratings, such as sapphire-based (SFBG) ones, much higher temperatures can be measured, reaching up to 2000 degrees Celsius [63][64][65][66]. Such gratings are suitable for applications for which the possibility of measuring high temperatures is essential [19,53]. However, sapphire-based FBGs have a stronger Bragg wavelength and temperature dependence than standard fibers, and thus the value of α = 0.023 nm…”

In this article, a cost-effective and fast interrogating system for wide temperature measurement with Fiber Bragg Gratings is presented. The system consists of a Vertical Cavity Surface Emitting Laser (VCSEL) with a High Contrast Grating (HCG)-based cavity that allows for the fast tuning of the output wavelength. The work focuses on methods of bypassing the limitations of the used VCSEL laser, especially its relatively narrow tuning range. Moreover, an error analysis is provided by means of the VCSEL temperature instability and its influence on the system performance. A simple proof of concept of the measurement system is shown, where two femtosecond Bragg gratings were used to measure temperature in the range of 25 to 800 °C. In addition, an exemplary simulation of a system with sapphire Bragg gratings is provided, where we propose multiplexation in the wavelength and reflectance domains. The presented concept can be further used to measure a wide range of temperatures with scanning frequencies up to hundreds of kHz.

“…Interferometer-based high temperature sensors are usually realized by fabricating micro-cavity structures using laser writing, mode field mismatch by mismatch fusion splicing, fiber tapers by electric arc discharge or oxyhydrogen flame, and so on. According to the different interference structures, high-temperature fiber-optic sensors can be divided into several types, including transmission type, such as Mach-Zehnder interferometers (MZIs), and reflection type, such as Michelson interferometer (MIs), and Fabry–Perot interferometers (FPIs) [ 10 , 11 ]. Most interferometric high temperature fiber-optic sensors can operate with higher temperature sensitivity (10–165 pm/°C) compared with FBG sensors thanks to the higher sensitivity of the optical phase difference (OPD) on temperature variations [ 10 ].…”

High temperature detection is a constant challenge for condition monitoring under harsh environments in optical fiber sensors research. In this study, the temperature response characteristics of guided acoustic wave Brillouin scattering (GAWBS) spectra in silica single-mode fiber (SMF) up to 800 °C are experimentally investigated, demonstrating the feasibility of the method for high-temperature monitoring. With increasing temperature, the resonance frequency of GAWBS spectra increases in a nearly linear manner, with linearly fitted temperature-dependent frequency shift coefficients of 8.19 kHz/°C for TR2,7 mode and 16.74 kHz/°C for R0,4 mode. More importantly, the linewidth of the GAWBS spectra is observed to narrow down with increasing temperature with a linearly fitted rate of −6.91 × 10−4/°C for TR2,7 modes and −8.56 × 10−4/°C for R0,4 modes. The signal-to-noise ratio of the GAWBS spectra induced by both modes increase by more than 3 dB when the temperature rises from 22 °C to 800 °C, which indicates that the proposed sensing scheme has better performance in high-temperature environments, and are particularly suitable for sensing applications in extreme environments. This study confirms the potential of high-temperature sensing using only GAWBS in silica fibers without any complex micromachining process, which has the advantages of strong mechanical strength, simple structure, easy operation, and low cost.
