A comprehensive temperature Drude theoretical mode has been established to study the temperature effects on the side-polished photonic crystal fiber (PCF) surface plasmon resonance (SPR) sensor. In the theoretical model, the temperature dependence coefficients of fiber material refractive index (RI), sensing film thickness and metal-dielectric function have been considered. The finite element method (FEM) is used to study the influence of side-polished depth, metal thickness, air hole size, and lattice constant on sensing performance with findings as following: (1) the dependence of the resonance wavelength on temperature is almost unaffected by duty ratio or lattice pitch of PCF; (2) the peak loss of the PCF SPR sensor with small lattice pitch (or increased duty ratio) is more sensitive to temperature variation; (3) for the sensor working in intensity interrogation mode, linear relationships can be found between the peak loss versus the RI and temperature. Moreover, we fabricate a side-polished D-shaped PCF SPR sensor by a wheel polishing setup, and the experimental results display a good agreement with the theoretical investigations. This study offers a detailed way to analyze the temperature effects on the sensor, and may lead to the better design and the data-progress improvement for D-shaped PCF SPR sensor.

建立了全面的温度Drude理论模型，以研究温度对侧面抛光光子晶体光纤（PCF）表面等离子体激元共振（SPR）传感器的影响。在理论模型中，已经考虑了纤维材料折射率（RI），感测膜厚度和金属介电函数的温度相关系数。有限元方法（FEM）用于研究侧面抛光深度，金属厚度，气孔尺寸和晶格常数对传感性能的影响，发现如下：（1）谐振波长对温度的依赖性几乎是不受PCF的占空比或晶格间距影响; （2）具有小晶格间距（或增加的占空比）的PCF SPR传感器的峰值损耗对温度变化更为敏感；（3）对于在强度询问模式下工作的传感器，峰值损耗与RI和温度之间可以找到线性关系。此外，我们通过车轮抛光装置制造了侧面抛光的D形PCF SPR传感器，并且实验结果与理论研究显示出良好的一致性。这项研究提供了一种详细的方法来分析温度对传感器的影响，并可能导致D形PCF SPR传感器的更好的设计和数据处理方面的改进。
