摘要(Abstract)：
通过引入几个较大空气轴,设计了几种全反射光子晶体光纤(toatl internal reflection photonic fiber).运用平面波展开法(plane-wave expansion method)和频域有限差分方法(finite-diflerence frequency-domain method)对它们的约束模式、有效折射率和归一化频率等特性进行了分析.结果表明当第一圈填充率(d/Λ)改变时其约束模式、有效折射率和归一化频率有明显的变化,对设计低损耗光纤有一定的作用.
关键词(KeyWords)： 全反射光子晶体光纤(TIRPCF);平面波法(PWM);频域有限差分(FDFD);有效折射率(Effective Index);填充率(d/Λ)
