摘要
利用基于多极法的数值模拟软件包对光子晶体光纤色散特性进行数值模拟和分析,发现通过改变包层空气孔直径d和空气孔间距A可以有效地调节光子晶体光纤的色散特性,即短波长零色散、近零超平坦色散和大负色散,得到了三种色散特性随光纤结构变化而变化的规律。
The dispersion properties of photonic crystal fiber （PCF） are sinadated and analyzed using of the software package basing on the nadtiple methods. three dispersion properties of PCF are studied including short wave zero dispersion; nearly zero ultra - flatten dispersion and high negative dispersion. It is fmmded that the dispersion properties of PCF can be modulated effectively by changing the pitch A and the air hole size d in cladding. The law of the dispersion property change with the structure is obtained.
