摘要
编程实现用于分析光子晶体光纤的频域有限差分法,数值模拟分析了典型的商用大模场光子晶体光纤(LMA-20型)的传输特性,包括模场分布、模场半径、截止特性、模场有效面积和数值孔径等,模拟计算结果与实际测试结果吻合很好。为商用PCF的理论分析提供了参考。
The finite difference frequency domain methods is implemented by using MATLAB in this paper.Based on the program,propagation characteristics of a kind of typical commercial PCFs( type-LMA-20 large mode area) such as cut-off property,mode field,mode field radius,effective area,are analyzed. The results of simulation agree with that of testing well.
