“…The temperature sensitivity reached up to 2.41 nm∕°C. 16 The sensitivity was greatly improved, but the fabrication process was complex. Liu et al implemented crystal induced RI modulation in sapphire-derived fibers and developed a F-P interferometer based on sapphire-derived fibers for ultrahigh temperature sensing, 17 but its sapphire cone cost was high.…”

We present an optical fiber Fabry-Perot (F-P) temperature sensor based on metal welding technology. The fiber sensor is composed of a single-mode fiber and a metal capillary that are encapsulated by metal welding technology. The relationship between the cavity length and sensitivity is analyzed theoretically. The experimental results show that the sensitivity of the fabricated sensor reaches 3.85 nm∕°C when the F-P cavity length is 171 μm. In addition, the sensitivity of the F-P temperature sensor increases as the cavity length of the F-P temperature sensor decreases. The proposed sensor fabricated by metal welding technology has the advantages of a high sensitivity, simple fabrication, simple structure, and low cost.

“…Among the numerous microfiber sensing devices, the optical fiber interferometers with complex structures have been carefully designed and fabricated relying on the microoperating systems with high spatial resolution [5]. Sensing devices based on a single microfiber are easier to fabricate, especially for the reflective fiber probes [6,7]. The localized surface plasmon resonance (SPR) effect of metal nanoparticles can greatly improve the sensitivity, and has been widely used in the development of various new SPR sensors in recent years [8,9].…”

A refractive index fiber probe has been proposed based on a long-tapered microfiber, which was obtained from a long single-mode microfiber by the oxyhydrogen-flame-scanning and stretching method using a multifunctional fiber tapering machine. This microfiber probe was used to detect the refractive index of seawater samples with different concentrations by demodulating the intensity of reflected light. The refractive index sensing performance of the long-tapered microfibers elaborated by the low refractive index UV glue distributing silver nanoparticles and silicon nanoparticles were experimentally demonstrated, compared and analyzed. More stable spectra and sensing performance was obtained for the silicon nanoparticles compared to that of silver nanoparticles. Although a high average refractive index sensitivity of 13.047 dBm/RIU was obtained for the long-tapered microfiber coated by two layers of silver nanoparticle UV films. However, the quality of the corresponding spectra was severely damaged, and the amplitude of light intensity at different wavelengths varied greatly. These problems can be well avoided for the silicon nanoparticle-decorated microfiber tapers, where the overall monotonic variation of the interference spectral intensity will greatly simplify the signal demodulation process and improve the reliability of the measurement results.

The verification of measurement errors has a big impact on the assessment of the accuracy of conducted measurements and obtained results. In many cases, computer simulation results are compared with measurement results in order to evaluate measurement errors. The purpose of our research was to check the accuracy of measurements made with a Fabry–Perot interferometer working in the transmission mode. In the measurement setup, a 1310 nm superluminescent diode light source, single-mode optical fibers and an optical spectrum analyzer were used. The influence of the length of the resonating cavity and refractive index on the envelope of the optical spectrum was investigated. A program was created that models the envelope of the optical spectrum on the basis of the length of the resonating cavity, the refractive index and the light source output spectral characteristic, which in simulation was assumed to have the shape of Gaussian distribution. After the simulation the program compares the simulated and measured optical spectrum. The comparison of simulated and measured optical spectra proved to be challenging due to the shift in the position of the central peak between the simulated and measured optical spectrum. There are two ways to perform model fitting: by adjusting the position of central peaks or minimums next to the central peak. It was observed that the second solution was more optimal and was implemented in the program.
