摘　　要：光子晶体光纤可广泛用于光纤通信系统、光电信号检测等有源和无源光器件中.利用Edlen公式分析了温度场对实芯光子晶体光纤的空气孔折射率的影响并应用热传导模型对光子晶体光纤石英介质在温度场作用下产生的热应力及折射率分布变化进行了分析,讨论了温度场变化导致光子晶体光纤中光脉冲相位和模式双折射的波动影响.与传统单模光纤相比光子晶体光纤中传播的光脉冲对温度具有较弱的敏感特性,在光电信号检测等无源器件中更具优越性.Potonic crystal fiber is widely applied in the active and passive devices of the fiber communication systems and the photoelectric signal detection. The air hole refractive index is analysed by Edlen formula. And the distribution of the quartz thermal stress and the refractive index is analysed by the heat conduction model in the solid-core photonic crystal fibers in the temperature field. The fluctuation of the pulse phase and mode birefringence in the photonic crystal fibers is also discussed. Optical pulse in the photonic crystal fibers is less sensitive to the tomperature than in general single-mode fibers. So it is beneficial in the active and passive devices in the photoelectric signal detection.
