摘要:在双包层近零色散平坦光子晶体光纤中引入微结构后,利用多极法对新的光子晶体光纤结构进行
了数值模拟。其中在包层结构参数不变的前提下,研究了纤芯中微结构的结构参数变化对色散特性的
影响。研究结果表明:通过优化纤芯结构参数,在不改变色散平坦度和色散平坦带宽的情况下,实现了
色散曲线的整体下移,进而达到正常色散。

Abstract:A microstructured core is introduced into the double-cladding near zero dispersion flattened photon-
ic crystal fiber, a new structure of photonic crystal fiber were investigated by using the mulipole method in
this paper. Without changing the cladding structure parameters, study the influence of microstructured struc-
ture parameters variation on dispersion characteristics. Numerical investigation indicates that through optimiz-
ing the structure parameter of the fiber core, without changing the dispersion flatness and flat dispersion band-
width,can realize that the dispersion curves move down overall,so as to generate the normal dispersion.
