对光子晶体光纤的后处理技术进行了详细的分析和讨论,包括拉锥、空气孔膨胀后拉锥、选择性空气孔塌缩。利用这些后处理技术,可以改变光子晶体光纤的结构参数,如空气孔大小、纤芯大小和形状等,制作各种不同类型的光子晶体光纤光器件。 After photonic crystal fiber post-processing technology for a detailed analysis and discussion, including the taper, the air hole after the expansion of the taper, selective air holes collapse. Using these post-processing techniques, various photonic crystal fiber optic devices can be fabricated by changing the structural parameters of the photonic crystal fibers, such as the size of the air holes, the size and shape of the core, and the like.
