摘要：
A surface plasmon resonance photonic crystal fiber-based highly sensitive temperature sensor is proposed. The surface plasmon resonance is induced by injecting toluene into the central hole and ethanol into the side holes coated with gold film. Optimal sensor sensitivity by optimizing the size and position of the air holes. The coupling mechanism and sensing performance of the proposed sensor are analyzed. The results indicate that in the sensing range of 0 degrees C-70 degrees C, the highest figure of merit (FOM) is 0.1169/degrees C and the average temperature sensitivity can reach 7.13 nm/degrees C. Such temperature sensor exhibits tremendous potential in the domain of temperature detection.
