A new concave shaped high refractive index plasmonic sensor with a micro-channel is proposed in this work, which comprises an analyte channel in the core hole. The sensor is elaborately designed to reduce the interference effect from the metal coating. Furthermore, the impact of the proposed structure on the sensitivity is also investigated by engineering the geometric parameters. Gold is widely used to fabricate plasmonic and metamaterial devices because of its chemical stability and compatibility. According to wavelength interrogation technique, this sensor can obtain a maximal wavelength sensitivity of 10,050 nm/RIU. In view of the excellent indicators of this sensor, it has important development potential in chemical and biological research fields.

“…The lines of the three tted curves are y 1 = − 10.42x + 2531.64, y 2 = -8.52x + 2336.89 and y 3 = − 9.14x + 2152.8. The slope of thetted curves for sensitivity at d 2 of 1.5 µm is -8.52 nm/%, which tells us that at d 2 of 1.6 µm is when the sensitivity is maximum, so that d 2 = 1.6 µm is the optimum size[23].…”

This paper presents a gas sensor that uses surface plasmon resonance (SPR) technology and a novel D-type photonic crystal fiber (PCF) structure to detect methane. The sensor's double-sided, side-polished gas holes are the key components for achieving large-area contact with external methane gas. The coating material chosen to stimulate the SPR effect was a gold nanolayer. To increase the sensitivity of methane gas detection, the researchers used polysiloxane-doped cryptane E as a coating material. The study analyzed the sensor characteristics using finite element analysis (FEA) and numerical analysis to examine the effect of optical structure parameters on the sensor performance. The numerical results demonstrate that the sensor has a sensitivity of 11.52 nm/% and a FOM value of 0.409 when measuring methane gas in the concentration range of 0–3.5%. The curve fitted shows excellent linearity. The sensor is a promising technology for the future development of gas leakage detection due to its low cost, simplicity, and real-time detection capability.

A highly sensitive and simple structure side-polished micro-structured fiber (MOF) refractive index (RI) sensor based on surface plasmon resonance (SPR) is proposed and studied by the finite element method (FEM). The gold nanofilm used to stimulate plasmons is directly deposited on the inner wall of the open-loop channel of a MOF consisting of an arrangement of six cladding air-holes. The sample analyte is arranged on the outer surface of the optical fiber to improve the utilization rate of the sensor and reduce the tediousness of operation. Meanwhile, in order to increase the leakage intensity of evanescent field, three large air-holes were introduced near the fiber core. Research has shown that the proposed sensor can achieve sensing detection in the range of 1.19–1.37 RI. The maximum sensitivity in the x-polarized direction can reach 12,500 nm/RIU, and its corresponding resolution is 3.64 × 10− 5 RIU. Moreover, it has a high linear response of 0.9944 within the RI detection range of 1.19–1.33. Obviously, the proposed sensor has a simple structure, wide RI detection range, and high sensitivity, which can make it widely used in biomedical and analytical chemistry.
