光子晶体光纤的空气孔膨胀和拉锥技术研究

摘要

光子晶体光纤的空气孔膨胀和拉锥技术是一种有效的改变光纤结构参数的技术手段.空气孔膨胀可以改变空气孔的填充比例,即改变空气孔直径和孔间距的大小,光纤拉锥可在保持空气孔直径和孔间距比例不变的情况下改变纤芯的大小.光子晶体光纤结构参数的可控性改变可实现一些特殊光子晶体光纤器件的制作,对进一步实现和挖掘光子晶体光纤的潜在应用价值具有重要的意义.%Hole inflation and tapering techniques have been rated effective methods to change the structure parameters of the photonic crystal fibers (PCFs). Hole inflation can change the air-filling faction, that is, the hole diameter and pitch of the PCFs and tapering can change the core diameter while preserving the cross section of the original PCFs. Controllaable-change of the structure parameters of the PCFs allows some special PCF devices to be made, and is of great signiricance to further the potential applications of PCFs.
