采用液晶超薄涂覆层的双包层光纤模型,利用耦合模理论对长周期光纤光栅涂覆层折射率、温度特性进行研究,并通过实验和计算机模拟,得出长周期光纤光栅透射谱谐振波长于超薄涂覆层折射率及温度的关系。
The response of a double-clad fiber model to temperature is studied using coupledmode theory. Through experiment and simulation, we obtain the relationship between the resonance wavelength of LPG's and the overlay refractive index and temperature. The experimental results fit the computer simulation results well.
