利用全矢量平面波法分析三角晶格结构空心光子晶体光纤(PCF)的结构参数包层空气孔直径d、包层空气孔间距Λ、包层的空气填充率F以及介电常数对光子带隙的影响。通过模拟计算发现,随着d、F、介电常数的增大以及Λ的减小,带隙宽度也随之增大。说明了采用何种参数配置能实现宽带隙的PCF,并模拟出在这些结构参数下的带隙分布图。
Using full vectorial plane wave method to analyze the structural parameters of hollow photonic crystal fiber (PCF) with triangular lattice structure, the diameter of cladding air hole d, the spacing of air hole of cladding layer Λ, the air filling rate F of cladding layer and the influence of dielectric constant on photonic band gap influences. It is found through simulation that as the d, F, the dielectric constant increases and the Λ decreases, the band gap width also increases. Described the use of what parameters can be configured to achieve a wide bandgap PCF, and to simulate the bandgap distribution under these structural parameters.
