本文是一篇教学论文, 旨在通过对具体实例中不同物理过程的分析来定性解释光导拓宽固体材料折射率引导光纤光谱、多孔光纤光谱、光子带隙光纤光谱和纳米线光谱的原理。

This is a tutorial-style paper in which simple explanations are presented to provide qualitative insight into the different physical processes that account for the guidance of light in the broadening spectrum of fibre types. These types include solid-material index-guiding fibres, holey fibres, photonic band-gap fibres and nano-wires.
