摘要

This paper presents the design and analysis of an extremely sensitive surface plasmon resonance (SPR) photonic crystal fiber (PCF) sensor for temperature measurement in nuclear reactors, ensuring safe operation. The sensor uses an alcohol mixture (ethanol and chloroform) with a high thermo-optic coefficient as the sensing medium, injected into the PCF holes. A gold-coated plasmonic layer generates resonance peaks, which shift in response to temperature-induced refractive index changes in the alcohol mixture. These shifts enable accurate temperature monitoring. The sensor’s structural geometry is optimized for high sensitivity, achieving a sensitivity of 12.4 nm/°C by using sapphire as the base material instead of silica over the temperature range of 10 °C to 60 °C that the range of the temperature in this research reactor, resulting in better thermal stability. The results were obtained through simulations using the full-vectorial finite-element method (FEM) with perfect matched layer (PML) boundary conditions. This design demonstrates its potential for reliable temperature sensing in nuclear reactor applications.
