A surface plasmon resonance (SPR) temperature sensor based on a photonic crystal fiber (PCF) filled with silver nanowires is proposed in this paper. We inject ethanol solution filled with silver nanowires into the grapefruit PCF to realize temperature sensing. The sensitivity of the sensor can reach -433/ by numerical simulation, and the experimental result is -160/. Simulations and experiments show that the wavelength of the resonance peak will blueshift with the invalidity of silver nanowires, and the resonance effect of the sensor will weaken. It can provide reference for the realization and application of other SPR sensors based on PCF.
本文提出了一种基于填充银纳米线的光子晶体光纤(PCF)的表面等离子体共振(SPR)温度传感器。我们将填充银纳米线的乙醇溶液注入柚子型光子晶体光纤中以实现温度传感。通过数值模拟,该传感器的灵敏度可达-433/,实验结果为-160/。模拟和实验表明,随着银纳米线失效,共振峰波长将发生蓝移,且传感器的共振效应会减弱。这可为其他基于光子晶体光纤的表面等离子体共振传感器的实现与应用提供参考。
