Simultaneous measurement of gas pressure and temperature based on Fabry–Pérot cavity cascading fiber Bragg grating

AIP Advances (2021)

Huiling Huang Hailin Chen Chao Jiang Xiaoshan Guo Simei Sun

A novel optical fiber sensor with the ability to simultaneously measure gas pressure and temperature is proposed and experimentally demonstrated. The sensor comprises a fiber Bragg grating (FBG) and Fabry–Pérot interferometer (FPI) cascading; the FPI consists of two sections of single mode fiber splicing a short quartz capillary with a gas channel prepared by femtosecond laser micromachining that circulates the Fabry–Pérot cavity with external gas. Because the open cavity FPI is only sensitive to gas pressure and extremely less sensitive to temperature, while FBG is only sensitive to temperature and insensitive to gas pressure, an extremely simple diagonal matrix of sensitivity is obtained. The diagonal matrix elements are temperature and gas pressure sensitivity, corresponding to 0.012 nm/°C and 4.14 nm/MPa, respectively. Experimental results show that the sensor structure can realize the simultaneous measurement of gas pressure and temperature and eliminate the cross sensitivity between the gas pressure and temperature. The proposed sensor has the advantages of compact structure, simple fabrication, and convenient packaging and has a wide application prospect in the field of simultaneous measurement of gas pressure and temperature.

High sensitivity temperature sensor based on enhanced Vernier effect through two parallel Fabry–Perot cavities

Applied Optics (2022)

Huiling Huang Xiping Zhu Chao Jiang Hailin Chen Jiao Song

In this paper, an enhanced Vernier effect temperature sensor based on two parallel Fabry-Perot interferometers (FPIs) is proposed and demonstrated experimentally. Among them, FPI1 is composed of a single-mode fiber (SMF), a quartz capillary, and AB glue filled in the capillary. FPI2 is formed by filling a capillary with polyimide (PI) solution and inserting two-segment SMF from both sides of the capillary. Since AB glue and PI have good thermal sensitivity, FPI1 and FPI2 are highly sensitive to temperature. Due to their different structures, the temperature sensitivity of FPI1 is negative, and that of FPI2 is positive. When FPI1 and FPI2 with similar free spectral range are connected in parallel, they will act as reference cavities for each other, resulting in an enhanced Vernier effect, which enlarges the sensitivity of the sensor more. In the temperature range of 40°C-58°C, the temperature sensitivity of the sensor is as high as -13.09nm/∘C, and the fitting coefficient is 0.9974. The experimental results show that in the enhanced Vernier effect sensor structure, only two FPIs with opposite temperature sensitivity are required, which does not increase the difficulty and cost of sensor manufacturing. In addition, the sensor has good stability and repeatability.

Tapered hollow‐core fiber sensor for monitoring axial strain, magnetic field, and refractive index

Microwave and Optical Technology Letters (2024)

Jiawei Gao Chao Jiang Longfeng Deng Li Li Chuanju Hu

Abstract A high sensitivity sensor is proposed to measure axial strain, magnetic field, and refractive index. Hollow‐core fiber (HCF) and single mode fiber (SMF) are fused together to form the “SMF–HCF–SMF,” then tapering HCF, and finally forming a sensor. The light in the sensor structure forms an antiresonant reflection optical waveguide mechanism. The sensor has particularly thin waist circumference, therefore the surface evanescent field of the sensor is easily affected by environmental parameters, making it particularly sensitive to environmental parameters. The axial strain sensitivity obtained by the sensor is as high as −31.87 pm/µε. The magnetic field sensitivity obtained by combining the sensor with magnetostrictive material Terfenol‐D in the range of 10–40 mT is 123.9 pm/mT. The sensor measures the refractive index of NaCl solution with a sensitivity of up to 2109.308 nm/RIU (RIU: refractive index unit). Additionally, the sensor has good stability and repeatability when measuring three physical quantities. The sensor has a compact structure, stable performance, simple manufacturing, and can measure multiple parameters in biochemical engineering, industrial structural health detection, and marine resource detection.

Ultra-sensitive temperature and pressure sensor based on PDMS-based FPI and Vernier effect

Optics Letters (2023)

Jiao Song Simei Sun Chao Jiang Ning Chen Wenbo Jiang

An ultra-sensitive sensor, based on two Fabry-Perot interferometers (FPIs), has been realized for temperature and pressure sensing. A polydimethylsiloxane (PDMS)-based FPI1 was used as a sensing cavity, and a closed capillary-based FPI2 was used as a reference cavity for its insensitivity to both temperature and pressure. The two FPIs were connected in series to obtain a cascaded FPIs sensor, showing a clear spectral envelope. The temperature and pressure sensitivities of the proposed sensor reach up to 16.51 nm/°C and 100.18 nm/MPa, which are 25.4 and 21.6 times, respectively, larger than these of the PDMS-based FPI1, showing a great Vernier effect.

Excited State Intramolecular Proton Transfer of 1-Hydroxyanthraquinone

Chinese Journal of Chemical Physics (2015)

Simei Sun Song Zhang Kai Liu Yaping Wang Miaomiao Zhou

The excited state intra-molecular proton transfer dynamics of 1-hydroxyanthraquinone in solution are investigated by femtosecond transient absorption spectroscopy and quantum chemistry calculations. Two characteristic bands of excited state absorption and stimulated emission are observed in transient absorption spectra with the excitation by the pump wavelength of 400 nm. From the delayed stimulated emission signal, the time scale of the intra-molecular proton transfer is determined to be about 32 fs. The quantum chemistry calculations show that the molecular orbits and the order of the S2 and S1 states are reversal and a conical intersection is demonstrated to exist along the proton transfer coordinate. After proton transfer, the second excited state of tautomer populated via the conical intersection undergoes the internal conversion with ∼200 fs and the following intermolecular energy relaxation with ∼16 ps. The longer component 300 ps can be explained in terms of the relaxation from excited-state tautomer to its ground state. From our observations, two proton transfer pathways via a conical intersection are proposed and the dominated one preserves the molecular orbits.

High sensitivity gas pressure sensor based on two parallel-connected Fabry–Perot interferometers and Vernier effect

Measurement Science and Technology (2021)

Xiaoshan Guo Wenhao Ye Chao Jiang Simei Sun

In this study, a highly sensitive gas pressure sensor based on two Fabry–Perot interferometers (FPIs) in parallel with the Vernier effect is designed and demonstrated. In the sensor, FPI1 and FPI2 were used as the detection and reference units, respectively. FPI1 and FPI2 have similar structures, both comprising a single-mode fiber and capillary splicing. However, the microaperture is processed on the capillary of the FPI1 with a femtosecond laser, enabling the external gas to enter the FPI1 cavity through the microaperture channel to realize the gas pressure measurement. The Vernier effect is achieved by superimposing the reflective spectra of FPI1 and FPI2, which have a small cavity length. The gas pressure response, repeatability, and stability of the sensor structures were investigated. The sensitivity of the sensor was improved owing to the Vernier effect. Experimental results indicate that the sensor sensitivity is up to 47.76 nm MPa−1, which is 11.9 times that of a single FPI1 sensor without the Vernier effect. The measured temperature cross-sensitivity of the sensor is approximately 5.1 kPa/ °C. In addition, the sensor has the advantages of simple manufacturing, robust structure, and stable operation. Finally, the manufacturing method of FPI and the parallel connection mode of FPIs could also be used in other sensing fields, providing an alternative design scheme for high-sensitivity sensors.
