摘要
建立了空芯带隙型光子晶体光纤残余双折射理论分析模型,采用全矢量有限元法研究了光纤残余双折射产生的原因,最后搭建实验平台对空芯带隙型光子晶体光纤的残余双折射进行测试,并对光纤双折射的波长依赖性和温度稳定性进行了探究。仿真与实验结果表明,纤芯残余形变是导致残余双折射的重要因素,残余双折射随纤芯椭圆率的增大而增大,同时残余双折射的波长依赖性显著,温度依赖系数为0.3×10-9/℃。
Abstract
The theoretical model of residual birefringence in air-core photonic-bandgap fiber (PBGF) was established, and full-vector finite element method was used to analyze the causes of introduction of residual birefringence. Finally, the experimental system was established to test the PBGF’s residual birefringence, and also its wavelength dependence and temperature stability were analyzed. Comparing the experiment with the simulation results, it was found that the core residual deformation of PBGF is an important factor leading to the residual birefringence, and the higher the elliptical core rate, the greater the birefringence. At the same time, a significant wavelength dependence of the residual birefringence on the wavelength is observed and the temperature dependent coefficient is 0.3×10-9/℃.
