摘要
利用平面波展开法对全内反射型光子晶体光纤的模场分布进行了理论分析和数值模拟,发现通过改变光纤包层结构能够改变模场分布和色散特性,并且利用其特有的"无截止单模"特性。
The mode distribution on TIR-PCF is analysed and simulated by means of plane wave expansion method, it is found that the mode distribution and dispersion property are different with the change of PCF cladding structure. With the guide of its ＂endless single mode＂ characteristic, the PCF of large mode field has been designed.
