“…SPR is effectively used in plasmonic nanostructure sensors. Researchers have designed various SPR sensors using the unique property of SPR [22]; for example, waveguide or fiberbased RI sensors such as prism-coupling SPR sensors [23,24], metal-insulator-metal (MIM) waveguide-based sensors, a periodic array of rod-shaped plasmonic sensors [10,25], fiber Bragg gratings [26,27], microring resonators, and plasmonic PCF sensors [26]. SPR biosensors can detect biological samples near the metal surface using the resonance mechanism [28].…”

This article describes a photonic crystal fiber (PCF) temperature sensor that utilizes a flat, metal-coated trapezoidal surface. The PCF is made up of two layers of elliptical air holes and a polished trapezoidal surface that allows temperature sensing. An external sensing approach is used to deposit a thin silver layer on the reflective surface, while a thin SiO2 film acts as an oxidation-resistant coating. The top elliptical air hole serves as the interface for energy transformation from the core-guided mode to the surface plasmon-polariton (SPP) mode. Simulations carried out using the finite element method indicate that the proposed SPR-PCF temperature sensor can achieve a maximum temperature sensitivity and resolution of up to 5200 pm/°C and 0.01923 °C, respectively, across a temperature range of 10 to 60 °C. This research has significant potential for sensor design and real-time temperature remote sensing applications.
