本文提出了一种完全不同类型的光波导结构，其中光被二维光子带隙晶体限制在低折射率区附近。波导由一个额外的空气孔组成，该空气孔呈规则的蜂窝状，沿细石英玻璃纤维的长度方向排列。基于这种波导机制的光纤支持具有非凡特性的导模。
A fundamentally different type of optical waveguide structure is demonstrated, in which light is confined to the vicinity of a Low-index region by a two-dimensional photonic band gap crystal, The waveguide consists of an extra air hole in an otherwise regular honeycomb pattern of holes running down the length of a fine silica glass fiber. Optical fibers based on this waveguide mechanism support guided modes with extraordinary properties.
