光子晶体光纤的基模色散特性研究

Study on dispersion properties of the fundamental mode in photonics crystal fiber

通过Monro等提出的一种半矢量方法建立了光子晶体光纤的本征方程,解本征方程后计算了三角形光子晶体光纤的模场分布和色散曲线,并分析了光子晶体光纤的结构参数与波导色散的关系,得出了色散补偿PCF具有的结构特点。

The eigenfunctions of electromagnetic wave in photonic crystal fibers were set up by a semi-vector method proposed by Monro et al. After solving the eigenfunctions, the fundamental mode profile and the dispersion were calculated. The connections between the structural parameters and waveguide dispersion of PCF were analyzed, and then the structural character of dispersion compensation PCF is discovered.
