摘　　要：光子晶体光纤的拉锥是实现光子晶体光纤潜在应用价值的重要技术手段。通过优化普通光纤拉锥机的参数,利用"快速低温"拉锥法有效控制了光子晶体光纤空气孔的相对塌缩。实验中实现了两种不同光子晶体光纤的拉锥,光纤外径分别从原来的125μm拉锥到50μm和30μm,光纤的孔直径和孔间距之比基本保持不变,拉锥损耗小于0.4 dB。基于普通熔融拉锥机的光子晶体光纤低损耗拉锥为光纤器件的制作奠定了基础。Abstract： Photonic crystal fibers （PCF） tapering is one of the most important technologies to exploit the potential application value of PCFs. By optimizing the conventional tapering machine parameters, PCFs can be tapered using the ＂fast and cold＂ tapering method while preventing the hole collapse. Tapering of couple different PCFs were presented in the experiment, and the outer diameter of the PCFs were from 125 μm to 50 μm and 30μm, respectively. The d/A of tapered PCFs was almost the same with the initial PCF and loss was less than 0.4 dB. Low loss tapering PCFs based on the conventional tapering machine lays a foundation for the manufacture of PCF devices.
