中文摘要：
通过合理设计并采用改进的两次堆积法制备出了结构完整的空芯光子晶体光纤（HC-PCF）。从实验中测得的透射谱可以看出，所制备的光纤在450-1100nm波段出现了5条宽窄不同的带隙结构。令人欣喜的是，最后观测到空芯中有显著的绿光传出。将带隙传光区域由近红外波段移至可见光波段，既有利于实验中带隙的观测，又为空芯光纤在可见光波段的应用开辟了广阔的前景。
英文摘要：
Using the improved twice stack-and-draw technique, the hollow-core photonic crystal fiber（HC-PCF） with integrity structure has been fabricated. The transmission spectrum shows that five photonic band-gaps with different sizes have been shown within the wave band of 450 to 1100 nm. And the green light has been observed propagating in hollow-core remark-ably. The propagation wavefengths have been shifted from the near-infrared wavelengths to the visible wavelengths, which is in favor of the observation of photonic band-gaps in the experiment,and gives a wide outlook for application of hollow-core photonic crystal fiber at the visible wavelenths.
