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。

Post-processing techniques of photonic crystal fibers (PCFs) are discussed and analyzed in detail,including taper,taper after inflation,controlled hole collapse. Using these techniques,the configuration parameters of the PCFs can be easily changed,such as hole size,core diameter,core shape and so on. Many types of PCFs devices can be made by using these techniques.
