Study on dispersion compensation to a novel hexagongal core photonic crystal fiber

文章利用多极法对新型六角芯光子晶体光纤的色散特性进行了数值模拟与分析,研究发现,通过改变第一包层空气孔直径和空气孔间距,可以灵活地设计波长在1.55μm附近具有高色散值、大的负色散斜率和能在短波长内单模传输的色散补偿型光纤。数值模拟和分析表明,该光子晶体光纤在色散补偿型光纤方面具有广泛的应用前景。

The numerical simulation and analysis of the dispersion properties of a novel hexagonal core Photonie Crystal Fiber （PCF） are performed by using the multipole method. The study finds that dispersion compensation fibers with high dispersion value at wavelength around 1.55 and negative dispersion slope transmitted in single mode at short-wavelengths can be flexibly designed by changing the air hole diameter of the 1st cladding and the air hole pitch. The numerical simulation and analysis show that this type of PCF will find extensive applications in dispersion compensation fibers.
