Abstract

In order to solve the problems of oxidation of the metal film coated on the outer surface of the photonic crystal fiber and the low sensitivity of the sensor, a side polishing temperature sensor based on surface plasmon resonance is proposed. First, the sensor is modelled with a metal coating on the side of the optical fiber of the sensor, using a temperature sensitive liquid as the temperature sensing substance. Then, simulations were carried out to calculate the structural parameters of the optical fiber and the effect of the metal material on the resonant wavelength of the loss spectrum. By comparing the sensitive sensing of different metal films, gold was chosen as the surface plasma sensing material. Finally, the sensing characteristics of the sensor are simulated using the finite element method. The results show that when gold is used as the surface plasmon material, the wavelength range is 675–1117 nm, and the high sensitivity sensing in the temperature range of 0 °C–60 °C can be realized. When the temperature is 0 °C, the maximum spectral sensitivity is 24.6 nm °C−1. The designed sensors have excellent performance and can be widely used for temperature sensing.

基于表面等离子体共振的D型微结构光纤温度传感器

为了解决光子晶体光纤外表面金属膜氧化和传感器灵敏度低的问题，提出了一种基于表面等离子体共振的侧面抛光温度传感器。首先，使用温度敏感液体作为温度感测物质，在传感器的光纤侧上用金属涂层对传感器进行建模。然后，进行了模拟计算，以计算光纤的结构参数以及金属材料对损耗谱共振波长的影响。通过比较不同金属膜的敏感度，选择金作为表面等离子体传感材料。最后，利用有限元方法对传感器的传感特性进行了仿真。结果表明，当金用作表面等离子体材料时，波长范围为675–1117 nm，并且可以实现0°C–60°C温度范围内的高灵敏度传感。当温度为0°C时，最大光谱灵敏度为24.6 nm°C−1。所设计的传感器具有优异的性能，可广泛用于温度传感。
