摘要:
利用有限元法研究纤芯含有空气孔缺陷光子晶体光纤的色散特性.结果表明,引入空气孔缺陷可增加波导色散作用,改变色散曲线斜率;当空气孔缺陷的直径增加时,色散曲线将会下移,因此通过适当选择小孔直径,可实现色散平坦的光子晶体光纤.光纤的零色散波长可通过改变光纤的包层空气孔占空比和小孔缺陷在纤芯中的位置而改变.该调节光子晶体光纤色散的方法对用于超连续谱的产生具有借鉴意义.
Abstract:
Dispersion properties of photonic crystal fiber with an air-hole defect core have been investigated by using the finite element method.The numerical simulation results indicate that the appearance of the air-hole defect has enhanced the waveguide dispersion,and changed the slope of dispersion to achieve a flat dispersion.It is also revealed that the dispersion curve downshifts with continuously increasing the diameter of air-hole defect,and there exists an optimal value with which a flat dispersion could be achieved.The zero-dispersion wavelength of photonic crystal fiber could be tailored through either changing the air-filling fraction in cladding or moving the air-hole defect away from the origin.These strategies of engineering the dispersion are particularly useful for the supercontinuum generation application.
