Abstract
A D-type photonic crystal fiber optic temperature sensor incorporating a gold nanowire was developed. The design and optimization process utilized the finite element method to refine key sensor parameters, including the diameter of the air holes within the fiber, the dimensions of the gold nanowires, and the spacing between the air holes. Through this optimization, the optimal structural parameters were determined. The temperature sensing properties of the sensor were investigated, demonstrating a sensing capability within the range of 10–50 °C, achieving a maximum sensitivity of −19.0 nm/°C. The sensor exhibits notable performance, characterized by a straightforward structural design and a fabrication process of relatively low complexity, highlighting its strong potential for applications in temperature sensing technology.
