摘要
优化设计了一种由两种不同大小的空气孔组合而成的双包层六边形空气孔格点光子晶体光纤,并研究了该类光纤的几何参数对色散的影响。结果表明调节包层中空气孔的大小及孔间距,可以容易调节色散及低色散带宽、非线性等性能。优化设计可以得到在C和L波段近零平坦的色散,其色散变化为(0±1.8) ps·km-1·nm-1。
Abstract
A double cladding photonic crystal fiber with hexagonal air hole lattice, whose claddings are made by two different sizes of air holes, is designed and the influence of the geometric parameters on its dispersion and low dispersion bandwidth are investigated. The results show that the dispersion, low dispersion bandwidth and the nonlinearity are easily tailored by adjusting the two different sizes of air holes in the cladding as well as the pitch. The near-zero dispersion of (0±1.8) ps·km-1·nm-1 at C and L band can be obtained by optimizing design.
