We have observed a numerical simulation of the PCF-SPR sensor detecting alcohol concentration at low temperatures. The investigation was carried out using the finite element method on the PCF-SPR geometric structure. We use a simple geometry structure of the sensor by using fused silica and gold as the sensor’s core and plasmonic material. Observations were made in the alcohol concentration range of 15%, 40%, 60%, and 70%. In the literature, we find the refractive index of each alcohol concentration and input its value into the proposed sensor. The proposed sensor shows that the sensor has a sensitivity in detecting alcohol concentrations at low temperatures of 91 nm/%. In the end, we obtained the optimal sensor components and the sensor can detect the alcohol concentration at low temperatures

“…It is worth mentioning that the reason we choose −30–40 °C as the temperature detecting range is for the consideration of both toluene characteristics and sensing performance. The melting and boiling point of liquid toluene is −94.9 °C and 110.6 °C, respectively [ 31 ]. Toluene remains chemically stable in this temperature range when sealed.…”

A compact temperature-refractive index (RI) flat photonic crystal fiber (PCF) sensor based on surface plasmon resonance (SPR) is presented in this paper. Sensing of temperature and RI takes place in the x- and y- polarization, respectively, to avoid the sensing crossover, eliminating the need for matrix calculation. Simultaneous detection of dual parameters can be implemented by monitoring the loss spectrum of core modes in two polarizations. Compared with the reported multi-function sensors, the designed PCF sensor provides higher sensitivities for both RI and temperature detection. A maximum wavelength sensitivity of −5 nm/°C is achieved in the temperature range of −30–40 °C. An excellent optimal wavelength sensitivity of 17,000 nm/RIU is accomplished in the RI range of 1.32–1.41. The best amplitude sensitivity of RI is up to 354.39 RIU−1. The resolution of RI and temperature sensing is 5.88 × 10−6 RIU and 0.02 °C, respectively. The highest value of the figure of merit (FOM) is 216.74 RIU−1. In addition, the flat polishing area of the gold layer reduces the manufacturing difficulty. The proposed sensor has the characteristics of high sensitivity, simple structure, good fabrication repeatability, and flexible operation. It has potential in medical diagnosis, chemical inspection, and many other fields.

“…The proposed design uses the partial filling technology [ 20 ] to infuse refractive index sensitive liquid materials selectively into the second, third and fourth layers of air holes closest to the gold coated layer so that the surface plasmons can efficiently and effectively propagate through the metal-dielectric surface. First, the UV glue carried by the mental tip is aligned with the air holes of the target PCF.…”

This paper proposes a highly sensitive surface plasmon resonance (SPR) refractive index sensor based on the photonic crystal fiber (PCF). The optical properties of the PCF are investigated by modulating the refractive index of a liquid analyte. The finite element method (FEM) is used to calculate and analyze the PCF structure. After optimization, the fiber can achieve high linearity of 0.9931 and an average refractive index sensitivity of up to 14,771.4 nm/RIU over a refractive index range from 1.47 to 1.52, with the maximum wavelength sensitivity of 18,000.5 nm/RIU. The proposed structure can be used in various sensing applications, including biological monitoring, environmental monitoring, and chemical production with the modification and analysis of the proposed structure.
