摘    要:为了从理论上分析和推导光纤宏弯曲损耗与温度的关系,采用了一个平板波导近似的弯曲损耗模型,对单模光纤的宏弯曲损耗和弯曲半径、波长以及温度的关系进行了分析和仿真,得到了弯曲损耗随弯曲半径的减小而增大,波长的增大而增大,温度的升高而减小的结论。该结论对光纤弯曲损耗在温度传感器方面的应用研究起着重要的参考作用。

关 键 词:单模光纤  弯曲损耗  弯曲半径  波长  温度

Abstract:In order to derive the fiber from the theoretical analysis and macro bending loss with temperature,a slab waveguide approximate macrobend loss model is adopted for analyzing and simulating the relation between the macrobend loss of standard monomode fibers and radius of curvature,wavelength and the temperature.The conclusion is that with the reducing of bending radial,the increasing of wavelength and the lower temperature,the bending loss is increasing.This conclusion can be used as important research references of fiber bending loss in temperature sensor.
Keywords:single-mode fiber  bending loss  radius of curvature  wavelength  temperature
